 Ah, indeed, I didn't even know about "git branch -dr" combination, even
though this makes sense and it's less drastic than "git remote rm".

 I'm afraid I still don't understand what this risk actually is. Surely you
can't accidentally operate on xanadu/whatever instead of whatever? I.e.,
even if TAB completes to xanadu/something (which normally would require
typing at least "x" in the beginning already), could you really not notice
it somehow?

 I'd recommend doing this relatively often because having outdated local
information about the remote repository can be quite confusing.

 Just to establish some vocabulary, Git calls them "references", or "refs".
"Tags" are something quite different.
