Exactly this. Even though I don't use git-bug anymore, I'm still a sponsor. I desperately want an issue-tracker-in-.git to become a standard.

Issues and CI are the only lock-in. The latter is legitimate because you're using someone else's CPU, but every developer has the tooling to "git diff" and write comments if we could just agree on a format.

I have trouble wrapping my head around how to make it so the public can create an issue in your git repo.
