Who cares?  If the user wants to go up and it does not belong to any VCS
then we can detect it without vc-*-root, and if the user wants to go up
but it belongs to another backend, I see no reason to disobey the user.

I.e. the functionality of "going up" is fine, but it does not require
the introduction of vc-*-root.
