A collection of EUIV Mechanics currently unimplemented in EUV

[AntarcticRanger]

My problem with cultural unions is that they feel like sort of a nothing mechanic. Like I reach a certain point and then suddenly accept everyone and then that's my culture group dealt with for the rest of the game. When in reality I think culture, especially local non-primary cultures, should become more important over the course of the game, as we shift away from medieval views of culture and towards more modern views.

Fundamentally the point of cultural unions is to differentiate how you assimilate foreign cultures vs very similar cultures, since you very much want to be assimilating them, what with how the price to accept cultures depends on their size relative to your primarily culture.
I don't think culture unions do that very well, but I very much believe that there needs to be  a mechanic that does this. Castilian assimilating Aragonese should have the possibility of being very different than them assimilating Andausian. And in addition, Aragonese was historically assimilated, it wasn't just accepted.

Building an empire where they don't want to integrate all the cultures in their culture group.

Roleplaying, wanting to mess around with a different playstyle, imposing personal challenges on themselves, hunting for some hypothetical achievement...

Sorry, do you mean EU4 cultural unions (what me and SAMaster have been referring to with that term) or EU5 Unify Culture Group here? The phrase used makes me think the former, but the references to assimilation make me think the latter.

I feel the same about the unify culture button, after reaching a certain point I can just press a button, wait a few years, then suddenly a bunch of cultures and local dialects disappear?

Tbh, the root problem is probably the way culture exists in the game, it doesn't really represent anything tangible. All of the minor splits are made based on language/dialect rather than strict self-identity, but also we have a separate language system, but also the "Unify Culture" mechanic seems to represent unity in self-identity rather than language?
