It looks like git-svn has mostly killed SVN(*), but commands like "git svn find-rev" and maybe "git svn log" will continue to be useful for projects that already migrated to git.
So I'm hoping to find time at some point in the future to port some non-libsvn-dependent parts over to C, and maybe improve things (like having find-rev work across branches).
Not sure when I'll have time (because I barely have time for existing FLOSS projects), but it's something I'd like to do at some point because Perl5 startup time is atrocious...
(*) unfortunately centralization has become stronger,
and I'll continue working on killing centralization :P
