Yes.  Playing fast and loose with our trunk commit guidelines has
resulted in some permanent damage to the ancestry.

Monticello repositories don't support duplicate names, but it also
can't easily check against that so it has to be up to the committer
(although I suppose it could try!).

No.  We should work toward eliminating duplicate names rather than
supporting them.
