In addition to my prior offlist review comments, here's one more I 
noticed, while checking the -01:

2. Scope

    ECT Differences:  Use ECT(1) to request ECN congestion marking
       behavior in the network that differs from ECT(0), e.g., as
       proposed in [I-D.briscoe-tsvwg-ecn-l4s-id].  This is at variance
       with RFC 3168's requirement that ECT(0)-marked traffic and ECT(1)-
       marked traffic not receive different treatment in the network.
    ECT Differences:  Use ECT(1) to request more frequent ECN congestion 
       behavior in the network counterbalanced by a reduced response to 
each mark
       at the sender, both of which differ from ECT(0), e.g., as
       proposed in [I-D.briscoe-tsvwg-ecn-l4s-id].  This is at variance
       with RFC 3168's requirement that ECT(0)-marked traffic and ECT(1)-
       marked traffic not receive different treatment.
L4S alters both sender and network behaviour, not just network.
