Perhaps we could have some kind of category for distutils packages which marks them as system add-ons vs. site add-ons.
One approach would be for distutils to have a list of system packages built-in, depending on the Python release. That list would cover PyXML and email; perhaps others.
Of couse, taking the _xmlplus hack out of PyXML will cause backwards compatibility problems (regardless what the alternative hook is).
