+1, I agree SCE on its own isn't enough. Before I support adoption as a proposed standard I'd want real-world tests demonstrating the value. I believe SCE has potential similar to L4S by providing a similar fine-grained congestion signal, and that it does so in a much cleaner way.
But there's a big gap between "has potential" and "has proven benefit" that I'd want to see filled before it's an RFC. That said, I would like to see experiments go forward, and I would like to see this become an active draft that a wg owns, so that if the experiments do prove there's utility that can be captured, it has a good path forward. I have concerns about L4S, and so my relief is about seeing a cleaner (and backward compatible!) proposal that does something that to me looks like a very similar effect. And I would very much like to see a bakeoff of some sort before committing ECT(1) to the use of L4S, since it seems to me there are some ugly problems down that road.

That's the entire thing why I am opposing the use of ECT(1) unless we're *really* *really* *really* sure there is something we want to blow it on. Using it for SCE for me is marginal benefit compared to what ECT(1) could be used for either. I think L4S is proposing enough novelty that it could be used for that, but I'm open for other suggestions.
