Yes, that's exactly what Aaron was worried about in the presence of inheritance:
that users would nest repos and that an existing branch might then start to
inherit the wrong repo.  The uuid idea makes inheritance more robust in the
presence of nested repos.

the uuid idea is just your "bit" idea, but with a lot more entropy :-)
