They're just useflags, equery properly displays their description, and
you can set them in pacakge.use equally well, so you don't have to
learn anything new. You get a new way to set them via variables in
make.conf, which I agree is debatable, but doesn't add complexity.

Well, categorizing useflags, esp. for packages with a lot of them,
certainly helps me when I need to review what to enable and what not.
