This reminds me of looking at rebase’s update-refs through a mirror, and I think is similar to what jj actually does. In particular, editing a commit that is reachable from multiple non-overlapping branches could update all of them.
A reasonable heuristic for safety is “pushed,” but I would also want to be able to edit something in @{u}.. even if it’s in @{push} so that I can force-push a new version. I suspect jj might also have heuristics we can borrow.
PS thanks all for being willing to borrow improvements! Reminds me of Neovim inspiring improvements in Vim, which I get to benefit from without switching :)
