Why do you want users to be forced to set this one specific value?
Okay, you also want to specify accel=kvm, but it does not break without,
just be slow.
qemu adds new revisions of the machine models. So sure, use this
mechanism to change defaults. Do we then also get q35 as default for
x86?

Also you need to specify the same machine model, or? And if this
default change is part of a new revision, this is already enforced.
