Hm, but all hosts and all guests need the ids, no?

It still seems restricting to use Linux as the ultimate source - and
that has nothing to do with visibililty. I'd say pulling from any
project is restricting: Why shouldn't we want to implement something in
qemu that Linux is not (yet) interested in, but other guests are?

Sure, but I always took this to mean "you can freely copy the
definitions", not "this is the authorative source".
