Wikipedia is built around the basic principle that if you just let everyone contribute, most contributions will be helpful and you can just revert the bad ones after the fact. This works for large communities that easily outnumber the global supply of fools, but below a certain size threshold, the sign flips and the average edit makes that version of Wikipedia worse rather than better.
So smaller communities probably need to flip the operating principle of Wikipedia on its head and limit new users to only creating drafts, on the assumption that most will be useless, and an admin can accept the good ones after the fact.
I'm not sure whether Wikipedia already has the software features necessary to operate it in such a closed-by-default manner.
For whom?

Wikipedia is prominent. Wikipedia articles in a language without much representation become prime examples of that language to those who read them.
By what unholy pact have you been beknighted as the bestower of wikis, my friend?
Why should a wiki be any different?
It's the same. Google translate uses trained AI models.
