The "general population", who does NOT pay for that privilege, gets the

One way is to null MPLS EXP for BE traffic and do QoS on that, and then
set EXP bits to something different for non-BE traffic. That leaves DSCP
transparent end-to-end on the IP packet.
But as I have read the discussion I do think that null:ing DSCP for all BE
traffic is the way to go, and keep the clean copy of DSCP to EXP within
the network for the customers paying for preferred treatment (or whatever
service you want to prioritize).
