I'm not sure we can do that without breaking gentoo. At least, it would be a _huge_ EAPI change. It would require a lot of PM work, would break our configuration format (if you want to do it properly) and probably have other side effects for running systems. And if you have followed NixOS development... you know that you can screw this up as well, because consistency is even more important if you really want declarative configuration. And I'm not sure there is enough interest in consistency in gentoo. People seem to be fine with micro managing USE flags in order to achieve a particular configuration state which can break arbitrarily on any update.
