The vast majority of developers working with git daily don’t know what a bare repo is, or that it exists at all. It’s not obscure knowledge as such, it’s just never come up for them as something they need.
The vast majority [0] of developers working with git daily have no mental model of git repos and just do a mental equivalent of copy'n'pasting commands and it's enough to let them do their work (until something breaks at least), so it doesn't seem like a particularly good indicator of whether something is obscure or not. There are many obscure things hiding in git, bare repos aren't one of those :)
