I don’t want to push the decision in either direction without looking into the details.

But I wanted to point out that there’s usually a third alternative between “no need for new documents” and “need a new RFC to describe the new version”. Explaining that the old protocol can be used and what the implications are may by itself be a useful document. In the specific example, is not immediately obvious to me for instance if the security consideration would somehow change, or if 0-RTT can or can not be used, etc.
