I agree.

The MSS option really has a different scope: it applies to all TCP 
implementations, high speed or otherwise and is essentially a mandatory 
clarification of earlier documents.  It is also valuable and important to help 
middle box implementers (who often futz with the MSS option) to get it less 
wrong.
