We are calling out TCP in this document (for example, here) as if it's the only 
alternative to UDP. RFC 9539 opens the door to alternatives that could also be 
used to avoid fragmentation problems, I think. 

Rather than explicitly calling out TCP, is it perhaps worthwhile being more 
open in the language to other alternatives to UDP?

I think I am not alone in hoping for a future in which all DNS messages between 
servers are carried over encrypted transports and that UDP/TCP is relegated to 
a long tail of support for legacy systems. It seems odd to ignore the 
possibility of that outcome. 

Much more minor point, you have "Joey Abley" in the acknowledgments section. If 
that is me, can we drop the "y"?
