>>Abuse needs an incentive. Can anyone think of a way to abuse L4S that provides a benefit to the abuser? (Other than the intended benefit of improved latency of course.)/

[JL] Wouldn't this application behaviour be readily identifiable? Also, if the app in question is queue building, ISTM that marking for NQB with a shallow buffer would not improve your app QoE.
