Good analysis.  I would say "git remote rm" should have removed
it and it would be a bug if it didn't.

To let you say things like "git diff remotes/origin" as a short-hand for
"git diff remotes/origin/master" (or whichever branch 'origin' repository
considered the primary one, which is determined when you cloned from it).
