Rabbit-hole warning. There isn't a real set of requirements anywhere for congestion control articulated any better than what's in 8085. Gorry and I looked through existing documents, realized that we're lacking here, leading to Gorry's [draft-fairhurst-tsvwg-cc-04](https://tools.ietf.org/html/draft-fairhurst-tsvwg-cc-04).

I don't think it makes sense to move text out of 8085 here. The entire point of a normative reference is so we don't do that. Is there any specific text that you have in mind, @ianswett?

The MUST here is so that an implementer is required to consider the UDP guidelines in 8085, but each one of those SHOULDs is evaluated individually. Simply saying SHOULD conform to 8085 is quite different than that.
