Those working on an L4S AQM (at least those in the cable industry) had to have a private WG for the last ~18 months, but now we're allowed to publish and talk openly again. Similarly, there's work under the covers on an L4S AQM in switch hardware. And I see external signs of work under covers on DSL access equipment (covers that I am not under any longer).
