Many thanks for the Yes position and for the positive comments on the shepherd writeup ... two comments as shepherd are inline ...

Thanks, --David

[David>] "new/untested" is the major reason.  The Transport Area has a practice of applying Experimental status to TCP changes until there is sufficient "soak time" (e.g., operational experience) to demonstrate that they don't break anything.

[David>] The "term of art" explanation is correct, e.g., see: https://www.iana.org/assignments/tcp-parameters/tcp-parameters.xhtml#tcp-parameters-1 .
