Background: I introduced the code to process VLAN 0 tags inline as 
normal traffic several years ago for 802.1p.

I'm referring to a mapping between IP DS bits and priority bits in the 
802.1p header. We have that for 802.11 to some extent already, IIRC.

Data point: OS X allows applications to request LEDBAT style congestion 
control (i.e. BitTorrent-style background traffic) for arbitrary TCP 
sockets through the priority/DS API there.

Yes, it has downsides but there are still potential use cases for it.
