John,

Network tokens provide the API between an application on a UE and the
network for the application to specify exactly the service it wants.
At the first hop in the network, the device can compress the headers,
use MPLS, put into some non-IP format, whatever it wants as long as
the user gets the service they've requested and correct protocol
behavior is maintained. If the operator wants to create a state for
every single flow in their network that's their prerogative, but good
luck scaling that to hundreds of billions of flows and getting it to
work seamlessly across mobile events-- the "connectionless" model of
IP replaced "circuit-switched" networks for good reason!
