I didn't say it shouldn't be done in rpmbuild, obviously that's where it 
really belongs to.

*Additionally* filtering them out on metadata generation would benefit 
existing users - apt and smart have done their own depsolving since day 
one and would benefit immediately, and yum since 3.2.x (for older versions 
it wouldn't matter much either way I think)
