You can separate wiki history quite clearly into pre-Wikipedia (c2 and friends) and post-Wikipedia. What disappoints me is that post-Wikipedia wikis are almost all "Wikipedia for <niche>", rather than something new.

As to the "something new" in this area, one thing that comes to my mind is some wiki-based experiment/game I seem to have seen once, where its own rules could be edited; I think it was framed as a kind of "social experiment", but I can't google it out now. Other than that, I'm afraid I'm still not exactly sure what you're trying to say, so I find it hard to discuss or acknowledge yet...
That said, for sure I seen the wiki tech used in more than one SCP-like narrative/worldbuilding case.
On the other hand, the c2 wiki was in fact a kind of encyclopedia already, so maybe a wiki just naturally matches with such structural model?
Two of the largest instances are https://agoranomic.org/ and https://blognomic.com/
You might be thinking of Peter Suber's Nomic.
That's touched on in SF, in "The Moon Goddess and the Son" (1979), by Donald Kingsbury. It's not developed there, just mentioned briefly.
