What makes it sticky? I just don't see it. The declarative Github Actions manifests?

I imagine very few people use the wiki, because it's so subpar.

The issues are a problem, but this is why I always thought issues should be a core part of the Git repo, checked into it, sort of how Fossil does it. And so should the wiki, for that matter.

Built an issue tracker like that, that persists state as an event graph in your repo in a dedicated branch. It is vendor agnostic and works offline:
