I disagree with your interpretation of the bar the document must meet. I believe I have clearly stated my concern. I will leave that judgment to the relevant ADs and IESG when they review the last call results.

Some people have clearly said that they read the existing RFC as permitting additions of EHs. That is not a matter of future RFCs, but of current readers. Other people have said that they read the text as clearly prohibiting such behavior. Which would at a minimum mean that any IETF effort to change it would be required to explain why it was acceptable and interoperable to change the rules. >> >> Given that the existing wording has been interpreted in different ways by different people, and that there is good reason to beileve that the differing interpretations will (if they have not already) cause interoperability issues, it seems to me incumbent on the WG to be clear about what it means. > > Can you please explain how that can create interoperability issues?
