Does it or does it not count as "allowing discovery to do its job" if you go to the directory, knowing that the directory is a bare one, and expect Git to work in it? I am guessing that your definition of "discovery" is not even consider if the current directory is a repository and always force the user to tell us with --git-dir or GIT_DIR. I am not sure that is realistically feasible (I am thinking of cases like "git fetch" going to the remote repository on the local disk that is bare to run "git upload-pack"), but if the fallout is not too bad, it may be a good heuristics.
