The game has already been brought to a playable&stable state couple of versions ago. Recent betas introduced some "new" (not really vital) features but also some new and resurrected bugs are popping up in the process. Calling it "early access" - let's say it is not what they promised it to be. The team no longer listens to suggestions not to mention making it part of the game. When you feel nothing is really definite and they are still open to constructive criticism - this is how I see EA. It was the same with other EA I took part with. And sure you can argue this is not what it means. TW officially denounced the community/team game development approach. The only thing they want is the free quality control team to catch bugs - there are plenty of new people here willing to help. I do it every now and then myself but I see - it's a bit cynical. You can release fixes, patches, and bug reports without calling your game EA.
Despite various polls, posts, and fanbase pleas for introducing features - TW either says this is too complex or not in scope. See, I also like playing vanilla (you mentioned that somewhere) but I no longer expect this game to be far off the current state. I have 1200 hrs in Bannerlord on my counter - 40Euro well spent. But with this potential, I must say I'm very disappointed with its current state, lack of depth, and slow progress.
So to wrap up - my opinion is: Finish the Game, release a stable version - and let modders add the flavor.
