This is used by "/usr/portage/profiles/default/linux/amd64/10.0" for example, so I have "cups" in default NON-DESKTOP profile like it was a mandatory useflag. Is it? I don't even have a printer and expect that profile to be the very minimum. This would rather be a useflag for targets/desktop/make.defaults imo. I see a similar discussion has happened 2 years ago, but I don't see a solution there.
