On the one hand bzr.dev and all the plugins are separate entities so it
is everyone for themselves.  On the other hand bzr.dev and the plugins
form a system.  Where a plugin chooses (for whatever reason) to depend
on a certain version of bzr.dev then clearly it is up to the plugin
people to watch changes in bzr.dev and react accordingly.  However, it
really ought to be announced that a change in bzr.dev numbering is about
to take place so that plugin people can react as needed.

For myself I would say that bzr.dev and all the trunks/mainlines of all
the plugins should be treated as a single system that needs to be self
consistent at all times

I guess there must be some flexibility already build in as bzr-svn
depended on bzr 1.6 and yet there was no complaint until the bzr.dev
number went from 1.7 to 1.8.

I agree though that as with the deprecation warnings having version
mismatch warnings for development versions that are removed for
distribution versions might be a good move.

The current situation where a one character change in bzr.dev can stop
an entire Bazaar installation from working is not practical.
