I could give you an IP address, and still want you to negotiate a
transport you support with a transport that IP address supports. I can't
know that answer, so it's not my business to specify the transport.

Ultimately, either you're solving the transport discovery problem, or
you're solving some other much more limited, DNS-focused case driven by
a particular example. I'm not sure why that would be useful if you can
solve the general case, but if so, it'd be important to explain that the
'applicability' of DNS-focused solutions.
