I agree that fast-import is probably ultimately a better solution for
this, but given that git-svn currently uses the output of every command
it forks off and that fast-import doesn't seem to give the same output,
changing git-svn to use fast-import would be a fairly sweeping change
that I didn't feel comfortable making without a better understanding of
git-svn.
