Looking at http://www.ieee802.org/3/cm_study/public/september04/agenda_2_0904.pdf (slides 24 onwards), there seems to be more overlap with the Congestion Management SG. There doesn't seem to be a P802.3ar yet, though Frame Extensions SG used that designator in some of their July material.
However, given that FE is considering adding about 500 extra bytes of overhead (!), increasing total frame size by 30% (and potentially including some fields that could be of use to RE), there ought to be some kind of liaison process at the next stage.
