Could it be that it is unused because Pyhon 2.5 was just released?  That is 
when these fields made it into Distutils.

So how do you specify an exact platform and Python version with setuptools' 
install_requires?  They are, IMO, used at the same level.

It is a little late now.  Those fields are part of Python 2.5 so they are 
going to be around for at least 3 more years (if the 2.3 to 2.5 timeline is 
any indicator). So how about doing something to actually *improve* the fields 
besides just complaining?

Going forward with (probable) modifications to the fields' allowed values, it 
should be fairly easy to expand the allowed values as the need arises since 
the current values are so restrictive.

Now there is a postitive attitude...
