I think this is a crucially important point and one that definitely
needs raising with the user.

The fact that Bazaar is hiding Subversion, Git and Mercurial
repositories behind Bazaar branches and the Bazaar UI is great.  The
fact that Bazaar is hiding Subversion, Git and Mercurial repositories
behind Bazaar branches and the Bazaar UI is a real pain the @rse.

So being able to use Bazaar to manipulate Subversion, Git and Mercurial
repositories is seriously great, but it should always be clear and not
hidden when a non-Bazaar storage is being used.  Not only is this
managing user expectations, it is allowing the use transparency of
knowledge about the system under manipulation.
