I've got some plans for patches to portage, at least for my own system.
This primarily includes USE variable tracking - keeping track of which use variables are used by each ebuild (this can probably be done through the use function.) Set this up as an optional check, separate from --update world to see if new USE configs are available.
I'll probably start hacking on this and submit the patches to bugzilla, but I'm not holding out much hope on having them added - Portage2 is pretty under way, is my understanding.
