I agree that the way you want to do packaging is fundamentally incompatible with build systems that do not resemble distutils. Perhaps since this is distutils sig some here are too used to distutils as the only model of how packaging might work. Beware that, when fighting monsters, you yourself do not become a monster... for when you gaze long into the abyss. The abyss gazes also into you.
I suggest letting the pep go provisional. If open source publishers, who are highly motivated to produce useful free software, are suddenly also motivated to publish broken build systems, and if you can't vote with your feet by picking an alternative package, then demote the pep.
