Killer Shrike

There's various ways, all w/ pros and cons. 
 
Most people would naturally go for an obvious and literal translation, fixating on the idea of "how do you make or interact with an extradim space in the Hero System" and thus go down the path of using EDM. This can be made to work, and I have also done it that way, but I think it is a somewhat naïve approach and focuses on using mechanics to model the SFX rather than reasoning from effects which is the more correct way to do things.
 
For me, the "bag of holding / handy haversack / portable hole / extradimensional object of holding more than you think it could" idea is mostly about carrying stuff. Bluntly, the BoH type of magic item in D&D is about allowing D&D characters to opt out of the encumbrance rules while carrying around  the ridiculous amounts of loot they have acquired. In campaigns where the GM doesn't bother to enforce encumbrance, you rarely see such items because the problem they overcome isn't affecting the players and thus they are not needed.
 
Fantasy Hero also has its version of encumbrance rules, but not all GM's enforce them at all or enforce them only partially. In a campaign w/ encumbrance being tracked, how much stuff you can carry without taking encumbrance penalties is a function of STR, and thus a bag of holding type item can be handled as nothing more than SFX for extra STR (0 END, IIF, Only to Offset Encumbrance Penalty For Things Carried Within It).
 
YMMV.
 
There are also other variant notions such as Newt Scamander's suitcase, which could be treated as a cool SFX for a Summon. Another approach for these sorts of things is as a fantasy SFX for a gadgeteer VPP (ala Batman's Utility Belt but with the justification of "magic xdim storage" instead of "Cuz I'm Batman"). And so on. At the end of the day, focus on what the desired outcome is, ask what mechanic most directly delivers that outcome, and the chrome / cosmetics is just SFX.

Actually, here are a couple of Fantasy Hero characters who are loose conversions from Pathfinder who have variant Handy Haversacks, defined as extra STR to carry stuff:

Ilusia (FH6e) Ilusia (PF1e)
 
Reyals (FH6e) Reyals (PF1e)

So...my "other COVID project" has been restoring an old truck that my dad purchased back in 1984.  A 1925 International Harvester Model S Speed Truck, to be precise.  All original, but in need of a LOT of love and attention.

Replaced the carburetor with a non-original but same era Stromberg SF-1 -- vastly more reliable than the original, which was renowned for cracking and leaking (which it had on multiple occasions).

Relined and restored the brakes, retuning all of the mechanical linkages.  This was easily the biggest of the jobs we had to perform -- a crazy amount involved there.

Re-wired the entirety of the electric system, including the mains (with era-appropriate wiring)

Fixed and remounted the lights and connection assemblies.
 
Replaced the generator cut-out (and was thrilled to find that the original generator was still perfectly functional)
 
Replaced all oil and lubricant with era-appropriate formulae.
 
Degreased (or at least began the long process of degreasing) the undercarriage.

Restored the dials and gauges in the cabin (in the process of re-wiring)...and found the original ignition key.

And got plates put onto it for the first time today, so it's officially road-legal.  Not an easy process in that I had to apply for a title in order to get the plates....the title my dad had gotten back in the 80's had completely incorrect information (1918 model year rather than 1925...wrong serial number/VIN - they had for some reason used the model number from the engine...etc).  Took it out for a 10 mile drive with multiple hills -- handled it like a champ.

So that's one project done....except for the cosmetics.  It's supposed to be a Red Baby -- found ample proof to support that as we worked through the restoration.  The re-paint to original will come in the next year or so...apart from the lettering (which I have the original schematics for), it'll be more or less like this:
 

So...that's been my past year of side project.  I now return you to your regularly scheduled gaming forum  

Yeo means young, thus Yeoman originally literally meant "young man" before it started taking on other meanings. 
 
If I was going with the idea of gentry as landed estate holders who lack peerage, and wanted a some-status social class below that but above serfs / peasants / no-status people, I would go with the classic term commoners, which is also a gender neutral term.
 
For a step in between gentry and commoners, people who have some land but are poorly integrated into the dominant feudal hierarchy I would go with the term freeholder. I would expect to find such freeholders at the fringes of the nation, in land that was acquired, annexed, or engulfed by an expanding feudal society but not outright conquered and thus was never fully integrated into the vassal / peerage model of the original nation and conquered lands where land was taken and reallocated. 
 
 
 

For such a very constrained use case, it would probably be better to use a Multipower vs a VPP. Maybe something like...
 
Domainu:  Multipower, 45-point reserve,  (45 Active Points); Formula Based Total Spell Usages per Day (Usages = (MP Reserve / 15) + ((CON + EGO + PRE) /10), rounded down; -1/2), Domain Spells Only (-1/4), Only While In Good Standing With Patron Deity (-1/4); all slots Side Effects, Always Occurs (AP/10 LTE; -1/2)

So...the Domain's you link to are meant to be used with the Dominine magic system, which is a relatively close conversion of D&D 3e style Clerics.

Having said that, it could be adapted to some other model of course.
 

In the USA, all military retirees (honorable service, 20 or more years or equivalent medical discharge) have some perks such as exchange / commissary base access, VA benefits, a pension, some burial privileges possibly including burial rights in Arlington (recipients of certain medals), a pension based upon highest rank attained, preference for hiring for federal jobs, and so forth. In particular, General and Flag officers generally continue to enjoy additional deference or consideration beyond what is strictly defined (particularly "famous" ones who played a prominent role in a conflict).
 
There are also less significant unofficial benefits, like some places will extend military discounts to retirees. Prior service (retired or not) might help get you out of a speeding ticket (allegedly, cough cough), or get you some deference in some situations...but again not something you can count on or insist on...sometimes it provides a bit of social greasing and sometimes it doesn't. 
 
This is probably worth a Perk in HERO terms for a gritty or realistic modern setting depending upon context. For instance, if your campaign is set specifically in Oceanside or San Clemente California access to Pendleton might be a narratively useful Perk, and so on for some other campaign explicitly near a military base you as the GM intend to make relevant to your campaign...
 
 
In addition to the obvious and legally protected benefits, and the less quantified but non-zero influence of social credit and "in-ness" from being prior military (whether you did 20+ and retired, or not) in an official context, a similar and in many cases more relevant benny is the social ties of useful contacts whom you once served with (some of whom may still be in service and others may have moved on to some other useful position in life), as well as civilian counterparts (who may still be in some position of authority within the government or a defense contracting firm). This will vary from individual to individual, but is certainly fodder for one or more Contacts in HERO terms. 
 
This is particularly true of General / Flag officers, many of whom continue to have some influence with former subordinates who are still in service; some also sit on policy or advisory boards, speak at various political action groups, act as a sort of Greek chorus on current military matters in the form of "expert opinion" provided to various new outlets, and so on. And, of course, some go on to a second act in politics, such as a political appointee to one of the intelligence agencies or the state department, or as an elected official...where their military background may or may not be relevant but at a minimum is a factor in selection or part of their election campaign narrative.
 
Hopefully some of that is helpful...

I spent a good thirty seconds wondering what it had to do with Killer Shrike.

Generally speaking, including a weak assertion which is easily picked apart or shown to be spurious, irrelevant, or poorly reasoned as part of a larger argument only serves to weaken the larger argument and undermine your general position.

Maybe my next character will buy an 8d6 Blast and 14 3 point Skill Levels; for a total cost 82 points he can have a 15d6 Blast at his normal OCV and DCV, or 12d6 with +6 OCV or DCV (or mix & match).
 
7 points more than a 15d6 Blast, but he doesn't need as much END since the skill levels have no END cost.
 
I'm not sure Spreading is the issue you perceive it to be, relative to other options.

The beam limitation in both 5th and 6th edition has 3 parts.  The first part states it cannot be spread, the second part states must be used at full power, and the last is that it explicitly states that it only creates a small hole in the character or object.  Most people only pay attention to the first part, but if your attack can do the second or third thing, it does not qualify for the beam limitation
 
When you take a limitation on a power it is affected by all things the limitation covers.  If it is able to ignore any aspect of what is listed on the limitation you cannot take it but may be able to create a similar limitation for a lesser amount.  Considering Beam is a -1/4 limitation that means an attack that cannot be spread but can be used at less than full power, and or creates more than a small hole gets a -0 limitation
 
If you took beam on all your ranged attacks you may want to reconsider it.  Having it on all your ranged attacks is actually quite limiting.   Not being able to reduce the damage when shooting at a target without a lot of defenses is going to make it difficult to take down a target without severely injuring or killing them.  Using a 12d blast on normal with only 2 DEF is going to put them in the hospital on the first shot and may cripple them. If you are using the disabling and impairing rules you have a very good chance of causing a permanent injury.  You are also going to be unable to bring down a barrier or blast open a door.  

An interview with the designers when 2e came out indicated that they had intended Spreading from the outset (but "Magneto attacked the disks") to provide some extra benefits to Energy Blasts as compared to STR.
 
The rules already say a limitation that does not limit saves no points.
 
 
This highlights how valuable skill levels could be.  +4d6 Blast can be +4 OCV, +4d6 or target multiple targets for 20 points.
 
8 3 point skill levels costs 24 points, and I can get +4d6, +8 OCV or +8 DCV - and it costs no END.  Maybe those 3-point skill levels are underpriced.  20 points for +4 levels that can add +4 OCV or DCV, or +2d6 Blast, at zero END, seems a bit more comparable, doesn't it?
 
Leaving aside Martial Arts as their own beast, but I can't buy the bonuses more than once.
 
 
I don't see that bullet knocking a man-size (or larger) hole in a chain link fence, or a brick wall.  However unrealistic, that's our "comic booky" default.

If you don't think "can't spread" has enough negative impact to justify the -1/4 limitation, deny the limitation.  I find Spreading adds a useful tactical option, both in its "mini-AoE" model and its "enhance OCV at the cost of damage" option.
 
I recall a suggestion (maybe a rule) that Beam also meant you just punched a tiny hope in a wall, etc., rather than knocking it down.  That would make Beams much less useful against barriers and Entangles.

You can put someone to 1/2 DCV or even 0 DCV with a PRE Attack. You can Flash targeting senses which impacts DCV in various ways. You can attack people from behind at 1/2 DCV (though some groups ignore that rule). Entangling, Grabbing, Stunning all affect DCV to 1/2 or 0. 
 
And so on. There's a DCV modifier chart somewhere in the rulebooks and supporting rules text that go thru all of this.

Spreading an attack is a useful capability of the system, IMO.
 
It is an optional rule, so if you are the GM and don't like it, you are well within GM discretion to not allow it. 
 
I never had any problem with it, personally. Other people's mileage may vary, obviously.
