To me, that's a non sequiter. PyXML has the same backwards compatibility
headache as any other third party module. If I had a module called
PyGraphs that needed weak references, I would have a problem if I wanted
it to work on Python 2.0 or 1.5.2.
Then you said: "Yeah, we only included XML because some people were very
vocal about including it for political reasons." Of course I was one of
those people so I still wanted to get to the bottom of this non
PyXML would have exactly the same backwards compatibility headaches if
there were no XML support in Python whatsoever. It's just a problem that
third party modules have. You either endure the pain or you make your
users upgrade to a new version of Python. As far as I can tell, those
are the only two choices.
