I don't think extra history is harmful at all, so the grafts could even
be temporary.  AFAIK, the extra history is only an aesthetic issue in
visualizers (and I actually like to see it myself).

Besides, git svn is just a workaround until the SVN repository is
replaced entirely by git :)

That would require renaming _existing_ branches to their "@SVN-NUMBER"
name; which would break mechanisms for tracking branches based on
refname.
