The appendix entry for RFC 7873 said:

    [RFC 7873] mentions DNS over TCP as a reasonable fallback mechanism when DNS Cookies
    are not available.

The phrase "reasonable fallback" doesn't sit quite right with me so I changed it to
"...as an alternative mechanism...".  Does that work for you or were you suggesting
that this point be made in the body of the document rather than only in the appendix?

I wondered about that as well.  I moved many of the standards track RFCs to the normative section.  I will highlight this change when the next version is posted and I hope someone lets us know if any of those are not appropriate there.
