while i agree with you (and i'm the one who set F's policy, back in the 
day), it's important to recognize achievements and advances where they 
have occurred. ICANN has "put something in writing" as you say:

https://www.dns.icann.org/services/axfr/

while RFC 7706 is terrible engineering and the IETF should be ashamed of 
publishing it, i think the least we can do is acknowledge that ICANN 
operates (and promises to continue operating) AXFR servers for the root 
zone. see again URL above. there is no need to make production AXFR 
queries for the root zone from "real" root servers any more.
