Hi Joel,

Authors, can you clarify whether it would be accurate for Jim to report "there have been implementations for many years, and multiple interoperability tests" ?

KT> Yes

Thanks,
Ketan

It would seem very strange to add an implementation section at WGLC, since by IETF policy they are removed before RFC publication.  (For context, the driving reason for removal is that they inherently become
obsolete.)

It is reasonable to include comments on implementation in the shepherd writeup.  That has to be short.  Authors, can you clarify whether it would be accurate for Jim to report "there have been implementations for many years, and multiple interoperability tests" ?

Thank you,
Joel
