When we get into such discussions, I question whether the API is
appropriate for libvirt-gconfig. This API should be focusing on
the mechanism for creating guest configs & trying to avoid policy
based questions, which can be left upto higher level apps/APIs.

The concept of 'default usb controllers' seems very policy based
to me & different hypervisors will have different views of this.

So IMHO we should not add this API
