Yeah, that latter point is really the killer argument. We don't want
to make people spend valuable review time on fixing uninteresting OID
conflicts. It's even more annoying that several people might have to
duplicate the same work, if they're testing a patch independently.
Given a convention that under-development patches use OIDs in the 9K
range, the only time anybody would have to resolve OID conflicts for
testing would be if they were trying to test the combination of two
or more patches. Even then, an OID-renumbering script would make it
pretty painless: apply patch 1, renumber its OIDs to someplace else,
apply patch 2, repeat as needed.

Hmm, could be helpful.
