It still seems very strange to import all branches, considering most
of them will likely never be merged and perhaps only a couple of them
are ready for merge.

That would create a repository on bitbucket containing all the
branches. I don't see why we should push anything but trunk.

And still no one with a feature branch has claimed that it would be a
problem to start with a fresh clone. The only thing we would lose
would be the history of the feature branches.
