I find the bzrbranch/branch split to be quite unsatisfactory. It has
lead to some [transient] bugs in fact.

Presumably you're suggesting this to make your life easier :) - what in
particular is causing you friction/headaches? (Just having the methods
there is at most unclear). Is it needing a more clear definition of what
you need to implement, or ???

These are already largely generic, for a given serialiser [but not as
generic as they need to be - see split inventories for instance, and
obviously bzr-svn and bzr-git are radically different].

If we don't want these on the public interface, I'd rather we do the
deprecation dance and give them _ names.

If instead we do want them public, but they in some manner interfere
with bzr-git and bzr-svn, lets address that directly.
