I see. For us it's actually more helpful if every single topic branch
is on the oldest possible state.

Yes, I fear there is no perfect solution to this. Someone also suggested
switching around the parent commits during a merge that updates one of
our branches to a newer base. That would solve the backmerge problem but
in turn break 'git log --first-parent'.
