I don't have a strong opinion either way as to whether we should adopt this (I notice there is not a specific milestone). If we do adopt it, it certainly would require a very thorough review by a reasonable number of people, because mistakes in such a document can easily find their way into implementations. I cannot commit to doing a thorough review.

I looked at the first example and it seems to be wrong. It is unclear how the mp parameter gets added to hi-entry 1.2. The example.com proxy is not in a position to know how Gold derived the new contact. I suspect Gold needs to provide the parameter in the 302 response. Moreover, I believe that would be a mapping from 1.1 (mp=1.1), not from 1.
