Yeah, I think we need to do this in DBus.  If we didn't, pretty much
all the existing configurations would be flawed; while services would
appear to work when communicating between statically typed languages
that don't need introspection, but fail when communicating between
e.g. a C service and a Python client.

I'll work on a patch.
