There are obviously always alternative design choices but why would you want
to include both a pre assigned device ID and a generated device ID in the

I think that reading this thread should provide you with ample reasons.
The instance ID in outbound has certain stability requirements that do
not strictly correspond to the lifetime of the hardware in use. The
other use cases answer very different questions, which include: is
this a stolen device, is this device authorized to use the networks,
etc... I'm certain those questions can be answered without a device
identifier traversing the network.
