Ofcourse. I can't think of a sane way to deal with commits that aren't
based on upstream. We can't expect the user to rewrite the history,
push and expect it to work. I'm only looking at perfect two-way
mapping for a restricted set of operations on the Git-side.

Yeah, I'm only looking at single-upstream SVN with stable revision
numbers, timestamps etc.
