I am not sure I agree that the result is the same.  Won't "bzr missing"
between mainline and feature branch give a useless set of information?

Also what is the technique of reintegration of feature branch to
mainline -- if it involves going outside the DVCS then isn't that an
admission of failure?

Experimental data is always good in this sort of discussion.  Your
success gives me confidence to experiment on this further.
