That doesn't change the fact that we need simple wrappers using C types
(at various levels: object_property_set_qobject, object_property_set,
qdev_set_*) to implement these type-safe accessors on top of dynamic
properties.

BTW, I don't really think it's possible to proceed on this except by
accepting compromises. We need to be the #1 QOM client, _now_ or it
will remain buggy & bitrot.
