I don't quite understand why this would be necessary.

Would "funky-slots" just be used in situations where ebuilds with the
same PV but different PVR have different slots?

Taking the gtk2/gtk3 example, I think the -r200/-r300 thing is only
used in libraries; applications use slot deps to select which one they
need. Paludis should not remove the -r200 version if it is still
referenced in the depgraph, correct?
