It doesn't have to be in the glep, but I think it'd be good to have. For example, if you allow use.mask or use.force in mixins, you can end up having unsatisfiable deps that repoman will never catch. Arguably, desktop profiles relying on having an useflag forced on a given package are already semi-broken: they'd be better with the useflag default enabled and proper usedeps, so the mask/force game doesnt seem really useful for mixins. It'd also be great to have "rules" ensuring all mixins commute, but I doubt that's easily doable.
