That would violate the properties and characteristics expected by the packet scheduler, wrt. to fair based fairness, rate limiting, etc.
The only legal situation where we can parallelize to single device is where only the most trivial packet scheduler is attached to the device and the device is multiqueue, and that is exactly what we do right now.
