The fear is unfounded. Bazaar has never actually *broken compatibility*
in its upgrades--at least not that I recall since 1.0. However, if
administrators of bzr servers choose to convert their repositories to a
format that older versions of Bazaar don't support, then it's true that
older versions of Bazaar can no longer access those repositories.
There would probably be a decision made when we switch to bzr what
repository format we were going to use, and then we'd stick with it
until such a time as all reasonably available versions of bzr supported
a newer repository format (most likely several years). Also, it's
looking like the 2a format may indeed be the last word in formats--we'll
see. At the least, the packs format is good enough for what we do with
Bugzilla, so we may not ever have to change.

Not really. Read the release notes and see.

Not true, it's had some minor releases. See the release notes. There
was a 1.6.1, as an example.

Except that last time I checked, Mercurial lacks built-in support for
bound branches--the fundamental CVS/SVN workflow (that you commit back
to the branch you checked out from with a "commit" command).

Here's the current list of top contributors to bzr:

That would depend more upon somebody committing development resources
to Testopia than a VCS switch, although switching to a DVCS would
certainly have some advantages. I agree it would be nice, though. :-)
Competent, Friendly Bugzilla and Perl Services. Everything Else, too.
