Having started messing around with this, one of the main advantages, to
me, of this approach is proper validation.
cpus.yaml has additionalProperties: true in it, which would have had to
be sorted out, or worked around, but creating a child-node with the
properties in it allows setting additionalProperties: false.

Mechanically, the conversion of the patch isn't difficult, but I'll still
wait for Rob to come back before sending a v2. But that v2 will more
than likely implement your suggestion.
