The whole point of Tasha's replacing racial ASI's with "do whatever you want - +2 & +1" (and Larian choosing to use it in BG3) was to stop encouraging or discouraging specific race & class matchups.
Yeah, believe me, that's fine. I'm all for providing more options to each race rather than pigeonholing them into traditional archetypes, but the argument was that Civil Militia was bad because human and half-elf are...popular picks??? Like, I really don't get the intention.
Human: If you wanted people to play human less, why wouldn't you just remove them from the game? I understand the potential frustration, but I feel as if people would pick human no matter what, because they're the race that's good for a first playthrough in a lot of people's minds. So, can we at least change their civil militia racial feature to some sort of choice feature?
Half-Elf: They have the same problem as humans with civil militia. This should just be replaced with a bonus proficiency, imo.
Who wants who to play human less? Why does a suggestion even exist to gatekeep races, of all things? Its so weird to suggest removing human as a race option, particularly considering they're the only intelligent race to actually exist irl.
Any racial that provides such encouragement/discouragement is therefor objectively bad.
This just isn't true at all, and you even provided examples of racial restrictions working in a positive way. Races
should be unique, distinct, and offer something that another doesn't have. That's why different racial options even exist in the first place. Tasha's, as the provided example, takes steps towards unifying racial archetypes but doesn't go so far as to scrub their identities and turn them into proverbial grey blobs. Homogenizing races into a do-anything doll just defeats the point of there even being different races to being with. Like, if any race can do anything, what do they even become, just a pretty face? What's the point?
The true crux of the matter is - Civil Militia is a fine racial attribute that serves as a very useful tool for classes that otherwise lack item proficiency. Just because it, or any other attribute, isn't universally applicable does not, in any way, mean that its bad or even deserving of rework or removal. If racial attributes are so crucially important, then the option to choose another combination of race/class exists and is a fine alternative.
