I really wish people would stop trotting out this false argument. Not everyone has the latest and greatest hardware. Rebuilds have a real cost to end users and as such we should use them wisely. > We tell everyone to use --changed-use and --newuse if they want > things to work, so they were probably going to rebuild anyway. Who tells everyone to use these flags and where? I never use these flags day-to-day, only if I need that specific functionality for that reason > Q.

If it is important (like if its default value changes > RDEPEND), then it would have required a revision anyway. Please stop trying to force workflows on people. Using that same logic, I can make the IUSE change in-place and it would be propagated in the next version bump. > Q.

I don't see any problem in portage/paludis/pkgcore handling things differently. That is the point of having different package managers, after all. > * emerge runs a bit faster.
