We went through this already, and I guess most of us agree that
the Subversion approach is not ideal for bzr.

The spec pointed out by Martin leaves it clear to me that he's
aware of these concerns, so I guess the to-be-proposed approach
is just a different way to achieve the same results mentioned
in the current spec.  The updated spec should clarify it.
