Yes I’ve run “git status”, “git log” and “git diff” on other people’s repo’s plenty of times to help debug things, so it’d be sad to see this stop working. It seems some basic readonly operations should still be supported.
It doesn't even have to be a repo. I do git diff --no-index all the time on arbitrary files, because it's simply configured the way I want, unlike some default diff or whatever command, that I don't even remember how to properly use.
