Because then they wouldn't see how wonderful bzr is compared to svn :)  The
workflows bzr calls "centralized with local commits" and "Decentralized with
shared mainline" look like a big step forward from SVN.  For the vast
majority of projects I work on that are currently SVN, the latter of those 2
models are exactly what would be used, pushing and pulling the exact same
remote branch.

FWIW, as a fairly recent SVN refugee and past light user of hg, my initial
reaction is that "push" should indeed default to the parent branch - but I'm
not yet versed enough with bzr to know if I would still agree with that in a
few months...
