Er, well, that *is* in fact the exact reason I want it.

I didn't put it exactly that way because I didn't expect anyone here to particularly care about round-tripping like that. But remember that I do a lot of stuff with repo surgery and conversion tools.

As a matter of fact (and this list is the first to hear about it) I'm working on code right now that massages a git import stream into a Subversion dumpfile. Soon, unless I hit a blocker I'm not expecting, I'll ship it.

Yes, there will be serious limitations and unavoidable metadata loss. But in every case *except timestamps* that loss is Subversion's fault for having a weak ontology. Timestamps are the one place git doesn't hold up its end.
