Thanks Rob!
Yes, initially this document was marked to obsolete rfc6810, but at the same time it mandated the use of the previous version as part of the Protocol Version Negotiation. Given that it may take a while before caches and routers both implement this new version, we decided to settle on leaving rfc6810 alone for now, and declaring it Historic/Obsolete later on. Alvaro.

This document looks like a bis document and used to obsolete the old spec till the last version (-07) but now neither updates nor obsolete it. Correct. Our AD told us that we could not both obsolete version zero and specify how to fall back from version one to version zero. Please feel free to take this up with our AD.
