This is the really dangerous case with L4S. I don't have numbers, but from looking at the platforms I have available to me, very few do ECN-marking. Considering that Apple has been beating the ECN-enablement drum for a few years now, there might actually be ECN-marking deployment soon. I'm in process of trying to figure out support for ingress/egress shaping and ECN marking on the most common BNG platforms, we'll see what that will result in. -- Mikael Abrahamsson email: swmike@swm.pp.se
