Hi Sander,

> - I object to not updating RFC8200 in any RFC that contradicts its content. If EH insertion should be accepted by this WG despite the objections then implementers reading RFC8200 need to know that a conscious exception has been made.

So, it sounds as if you are against publishing true facts. This draft describes an implementation and operational practice. I completely agree that it violates RFC8200, which standardises IPv6 for the Internet. I wouldn't object to adding an explicit statement of this to the draft, because that's also a true fact. But I would be very sad if the IETF is now against publishing factual information about actual practice that we are not willing to standardise, in line with https://tools.ietf.org/html/rfc2026#section-4.2.2 paragraph 2.

If we had standardised mechanisms for establishing limited domains, we could do better than that, but we aren't there yet.

Regards
   Brian Carpenter
