The difference, I think, is that it's easier in git to move the upstream
around: you simply start fetching from a different place. I'm not clear
on how that works in bzr (if it invalidates revnos or has other side
effects).

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.

That's good example of fully distributed approach. I can fetch directly
(actually, I cannot) from Junio private repository, I can fetch from
public git.git repository, either using git:// or http:// protocol,
I can fetch from somebody else clone of git repository: intermixing
those fetches, and revids (commit-ids) remain constant and unchanged.

So they (revids) do in bzr.
