OTOH, that would mean we'd need to introduce new device types if we
ever start to support a virtio 2.x standard. My understanding was that
we'll want separate device types for transitional and non-transitional
for two reasons: the bus which a device can be plugged into, and
changing ids. Do we really expect huge changes in a possible 2.x
standard that affect virtio-pci only, and not other virtio transports
as well?
