Hi all, 

I agree with Wes. 

Solving the SYN case is more problematic (e.g., consider an application relying upon MP_CAPABLE + FAST_OPEN). We managed to solve this specific issue in RFC8803 without requiring SYN-EOS/OOB, but that approach cannot be generalized. Having a tcpm WG document to cover the SYN case + discuss the issues of an OOB mechanism is useful.    

Cheers,
Med
