Actually I think I would need --1.9-rich-root as the branches have to
deal with Subversion.

Do I have to do this in the shared repository level, at the branches in
the shared repository level, or both?  (In this case of 4 branches in
the repository there are actually 5 .bzr directories.

I guess this then opens up the "should rich-root be the default"?  As I
understand it the difference between --1.9 and --1.9-rich-root is very
little unless you are dealing with Subversion in which case it is
critical.  This would militate in favour of making rich-root the default
since it doesn't hurt branches not dealing with Subversion and is the
right format for those that are.
