Moving upstram around does not invalidate revnos. Switching to different
upstream (ie. the head revisions are different) does. And this may
happen by doing a merge with the previous mainline as non-first parent
-- revnos are simply short aliases for revids, not persistent unique
idenfiers.

So they (revids) do in bzr.
