No, I think this is fundamental enough (along with the closely related issue #16) to require a demonstrated working solution, rather than mere aspirations towards future research.

SCE represents what such a demonstrated working solution might look like.  The difference is in the signalling mechanism, which remains RFC-3168 compatible by design.  L4S differs in this respect, which is why I consider it a fundamental design issue.
