Three thoughts …. 1) I don’t deeply care about this one way or the other but I think we should make it mirror the end marker bits. If the original publisher knows it is the start, or knows it is the end, it should add the marker. I think we should deal with start of track, start of group, at the same time as subgroup…

Mostly I don’t worry about how we spell it on the wire but FWIW … My gut feel is we are pinning to very weird implicit signaling by taking two things that have nothing to do with each other, the subgroup id and the object id, then saying if they are equal, it means some third thing. I’d rather just explicitly signal the third thing and not have it be some implicit convention on how to use the first two things.
