This sounds pretty interesting to me.  I think I even understand it.

You're hopefully hitting two really important targets here -- making
the stuff for the N+1 release always more installable, minus some
delta for some broken deps, which of course we can continue to make
less frequent; and not slowing down the ability for developers to
submit and build brand new stuff.

Since this is essentially No Frozen Rawhide v2.0, are you planning to
update that wiki page with this new proposal?
