It's one of those things I rarely need, but really need when I do need it. Commit numbers are an API and it's frustrating when I write something like "Fixed in commit xyz" or "Broken in commit xyz" or "Tested manually in xyz" and then after a rebase (Not a private rebase I asked for, but part of the CI routine), my comment makes no sense and Github says "We can't find that commit". You can paste it in manually but the context is lost, it's not in `git log --graph` anymore.
