Why ? If we build now a arch-all package and when the arch is up we could Break to the arch:all package.

Yes it is the same except that uefi is a full fledged arch with a sort of OS. But it will be nice to use the same thing I volontuer to implement this stuff, it will allow to build for instance firmware to arm easilly.

It is more the freestanding but just a little bit more.
