You're missing the point. I don't care about writing the actual
command line client in something like python, I care about being able
to actually use something that is not C to write the logic inside the
svn libraries, at least the bits that don't do any heavy computational

I'm not so concerned about people calling directly into libsvn_client,
but in allowing people to do so via language bindings, which are
considerably easier to construct if libsvn_client has a C API, as
opposed to the gymnastics that would be required if it was written in
