My go to with all projects like this is if it worth it if ends up it’s just you doing it for yourself. 99% of these projects attract no one but their creators.

So if you want to make a wiki for your own reference or to be able to link to in relevant conversation or for whatever reason you want to for yourself, and accept that no one else may not contribute or even care, go for it. If you just want this to exist but not put in the effort, you are probably better off seeing if someone else is doing something similar.
