IMHO, the document is both useful, and ready to move forward.

My personal nits, only editorial:

meta-query is not defined in this document, in RFC 1034, 1035 or
7719. Opinion: just "query".

Is it obvious for everyone that it is the decreasing order (most
preferred first)?

If this is because, with TCP, you have some certainty about the client
address, and therefore do not risk reflection attacks, then I suggest
to replace TCP by "transports that provide some guarantee about the
authenticity of the source IP address, such as TCP or DNS cookies".
