We just posted a new revision that we think addresses the recent GenART 
review comments.

Best wishes,

    Active Queue Management (AQM) mechanisms allow for burst tolerance
    while enforcing short queues to minimise the time that packets spend
    enqueued at a bottleneck.  This can cause noticeable performance
    degradation for TCP connections traversing such a bottleneck,
    especially if there are only a few flows or their bandwidth-delay-
    product is large.  The reception of a Congestion Experienced (CE) ECN
    mark indicates that an AQM mechanism is used at the bottleneck, and
    therefore the bottleneck network queue is likely to be short.
    Feedback of this signal allows the TCP sender-side ECN reaction in
    congestion avoidance to reduce the Congestion Window (cwnd) by a
    smaller amount than the congestion control algorithm's reaction to
    inferred packet loss.  This specification therefore defines an
    experimental change to the TCP reaction specified in RFC3168, as
    permitted by RFC 8311.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
