git status scales with the number of files in the repo. Ask HN - Are there any common git operations that scale with the number of commits?
It's Thursday and you wanna release a hotfix - but nope - all builds are failing because git can't cope with junk and your CI can't proceed. You then have to call BB instead and ask them to clean up, hoping they'll do it within the same day. Ah, exciting times.
Technically it has modes which need to scan all commits in the current branch as well, like the ones that grep for certain changes.
