"The draft does discuss both those issues, in Sections 5.1.6 and 7.1. Can you say what you think is missing from those?"

[BA] My issue wasn't really with Sections 5.1.6 and 7.1 (or with the TMMBR mandate).  It was with the text in Section 5.1, which seems to contradict the reasoning for mandating TMMBR.  As Magnus noted, TMMBR needs to be implemented to support congestion and flow control, which makes it more than just a performance concern.  That puts it in a different category from FIR, for example.
