There's a reason: simplicity. More than two part keywords simply are difficult 
to read, handle and are proving themselves pointless.
We just need to identify an operating system (or a variant of it) not a whole

Hmm well they are already being used, anyway, the following comes from 
rpm2targz:

RDEPEND="${DEPEND}
        userland_GNU? (
                sys-apps/util-linux
                sys-apps/which )"

Never thought about that actually, good point. I think last match would be 
good.

In the tree, to be decided by portage team if it should be in metadata/ or in 
profiles/ .
