Summary: Ready for publication as Proposed Standard

This document reads easily despite most of it being detailed lists. I have no objection to it moving forward, but I would like to check one thing:

The sparsity of detail at the end of section 2, where you call out potential interoperability issues and suggest that "implementers may wish to support transition mechanisms" is concerning. It might be worth being explicit here about the interoperability issues, and what a transition mechanism might look like, particularly if there's a chance of having to deal with a peer that won't implement what's described in this draft?

Did the group consider defining a couple of new code points and deprecating these two, to avoid that transition issue?
