At the time of this writing, there's no document that has been adopted
to update RFC8200 to allow for EH insertion/removal.

Therefore, it's actually the other way around: unless there's such
document (which there isn't, since such a document has never been
adopted by 6man), the onus is on folks trying to change the status quo.
And that case, progressing the document "as is" would be an outright
violation of our existing standards.

This has been repeated numerous times already.

I think we are at a point where the ADs should take action. Most
importantly Int-AD, since the spec being violated is RFC8200.

Thanks,
