Ok, I can see that point of view for make.conf. I can't agree with changes in other profiles though, as other profile will fall under the same category in USE_ORDER (in fact, it's the same thing, as the end USE from "defaults" comes from your selected profile and it's "parent" cascade, not taken from linux profile). But maybe you have it tested and know it's a problem. Have you? For the IUSE defaults vs make.conf (and other per-system override places) problem, we should really do something about it, it keeps coming up as an issue.
