The basic SCE concept could be used for L4S as well. I suggest to use an additional DSCP to mark L4S packets. The L4S sender/receiver can simply react to the SCE markings the same way that they now react to CE, with the difference that it's safer to react to SCE, because the signal is unambiguous, whereas CE would be ambiguous (could be set by either classic AQM/ECN node or by an L4S node).
