Because we are looking for cases where SCReAM (and other L4S transports) fail - and we have already found sufficient such cases to raise objections.  We don't need to look further.

The burden of proof is now on you (and the rest of the L4S proponents) to show that these problems have been overcome.    This will require *changes* to L4S, and testing of an implementation of that changed specification.

Sebastian merely listed a few general scenarios where we know L4S does badly.  Those are tests which you should run internally as part of your R&D cycle, and then present results of, in order to give us confidence that L4S can safely be deployed.
