Yes, and neither dataplane (x-data-plane=on) nor IOThread (-object
iothread,id=<name>) are finalized.
There was a discussion about -object and QOM on the mailing list a
while back. We reached the conclusion that -object shouldn't be a
supported command-line interface, it should be used for testing,
development, etc. So an -iothread option still needs to be added.
Actually I think that wasn't the conclusion.
"-object" is a supported command-line interface; we also support
hotplug/unplug nowadays for it, and the implementation makes QMP
entirely typesafe unlike netdev_add and device_add. We're using it for
iothreads and virtio-rng backends, and we'll add memory backends in 2.1.
However, the agreement was that "QMP methods" are the preferred
interface to work with objects. Properties and qom-get/qom-set are not
the way to build a command-line interface.
