Vim has merged contributions that are authored by some of the AI agent bots on Github. If you have the bots blocked, you will see a warning that parts of the repo you're viewing are contributed to by an user you have blocked (so, AI slop in this case).
Well, Vim git repo has that warning.
The fork is probably not going to go far, though. Vim has thousands of open issues and hundreds of merged PRs per month. I don't really see the fork picking up that momentum. But maybe it'll surprise, tho I doubt it.
