This is not a cache.  It's a hook that was meant (I think) to support VC
on remote file names (or maybe even within tarballs).  I don't know that
it's ever been used (then again, I'm biased because I never liked this
hook, so don't take my word for it).

That's right.  It's perfectly normal to have more than one backend
covering the same files.

That tends to be rather annoying, in my experience.

There is, it's called `vc-switch-backend` (except it doesn't prompt, but
lets you cycle, at least if it still works: I haven't used it in a long
while).
