Exactly why it belongs as a per-package BR, so we don't have to keep
track of it in every distro-version's exception list.

Everyone loves python, but how often is it necessary for the packages of Fedora Universe?

Here's my count of packages that require python after the fact:

$ (for f in $(find . -name \*.rpm); do if rpm -qp --requires $f | \
   grep "^(python =|/usr/bin/python)" > /dev/null 2>&1; then echo $f; fi; done) | wc -l

Core-6-x86_64:    74 / 2931 = 2.5%
Extras-6-x86_64:  135 / 4949 = 3.25%

Given that there are more .$arch.rpm packages than .src.rpm packages,
this means there are fewer than 2.65% of Universe that requires python
at runtime, so presumably about that many also *should* require it at
build time.  Not enough to require it in every buildroot.

My $0.02.

Thanks,
Matt
