The IETF RACK/TLP draft for TCP has a more dynamic hybrid of RACK ("time-based") and dupthresh ("packet-based") recovery: dupthresh is used at first, but then turned off when any reordering is detected. The idea being that a packet-based threshold is too sensitive on networks with moderate reordering. It would be easy to adapt this to QUIC. Along with the dynamic time-based reordering threshold that is a MAY in the QUIC spec right now iirc, this would go under the general heading of "reordering tolerance."
