It will be inelegant to have two code points for what is conceptually the same thing, but I think this is the best option, under the circumstances.

Au contraire: Windows TLS stack supports user_mapping and this mechanism appears to be somewhat in use. However, I agree that this falls into the category of extensions that need to be either deprecated or redefined for TLS 1.3.

Are you OK with deprecated followed by redefined with a new code point?
