Setting cannot_instantiate_with_device_add_yet=false looks much simpler
than implementing UserCreatable. My question is: may we do that, already
(once this series gets included), or is there something else holding us
from doing it?

Once you make something creatable with "-object", the API must not change anymore. So we would have to think twice about that.

Allowing -device may be okay, since in the (very?) long term -device can be replaced by -object. But -object is definitive.
