That said, the global USE flag manual copy to make.conf might get outdated; e.g. we plan to add USE=wayland as global default to gnome profile at some point soon(tm). Though make.defaults could be symlinked as well, I think to /etc/portage/profile/make.defaults Though these changes are rare, and it's a convenience anyways, e.g. you might have decided to globally enable wayland earlier already; or once the change is made you might counter it with a global disable in make.conf anyways.
