I can't claim to speak for the Python developers, but my guess would be
that the reason involves a license conflict between the Python license
(found at http://www.python.org/2.2.2/license.html) and the mx.DateTime
license (which is the eGenix.com Public License, to be found at
http://www.egenix.com/files/python/mxLicense.html#Public). I am not a
lawyer and so can't claim expertise on the subject, but I'm educated
enough to be able to read and understand legalese, at least; and my
reading of these two licenses suggests no significant incompatibilities
between them and, as far as I can tell, no legal reason why mx.DateTime
should not be included in the standard Python distribution.

On the other hand, Marc-André Lemburg is the owner of the mx extensions
package, and has presumably thought about this before. If mx.DateTime is
not part of the standard Python distribution, I would assume it's
because he requested that it not be included. I would love to hear his
thoughts on the matter.
