Yes for branches with very expensive working-trees, the mv and convert
should be a lot faster than a branch operation (though some of the
operations are the same).

I expect the convert_to_shared is simply a traversal of the revisions
in the branch and moving those not in the shared repository - then the
branch repository is simply removed.

convert_to_standalone would be the reverse, copy the ancestry of the
branch from the shared-repo into the branch.

Finding someone motivated to provide the feature who is familiar
enough with the inner workings of Bazaar is a whole different matter.
