Not at all. Any library module must only work with the Python version
that it ships with. It is up to the author of the module to impose
stronger portability requirements. E.g. Fredrik Lundh requires that
SRE continues to work with Python 1.5.2 and later; I require that the
PyXML code (minidom, pyexpat) works with Python 2.0 and later. If you
want to change SimpleXMLRPCServer to work with earlier Python version,
feel free to, but it is not required.
