I still don't see how this is any different than any other Python module. It's probably painful keeping NumPy compatible with old versions of Python also. How is PyXML unique in this? Paul Prescod

I didn't say that. NumPy has exactly the same issues. You proposed to tie newer versions of 3rd party modules to newer Python releases. I think it's wise to stay at least 1 or 2 releases behind. You don't want to lose your users because you forced them into a bad upgrade of the rest of their Python installation.
