Hi Steve, thanks for the comment.

I don't think I've seen anyone analyze that before, and would guess at the moment that it's too tenuous to try to work into this particular document at its advanced stage.

I would recommend continuing discussion or research on this in AQM, TSVWG, ICCRG or other appropriate groups at the moment, but not altering the draft.  At the ADs, and editors discretion, and if there seems to be working group consensus, it might be noted as a potential benefit for future exploration, but that's about the only impact I think might be appropriate to this particular document at its advanced stage.
