EDNS0 may literally be the worst possible role model here. It made DNS
a serious amplifier, the internet's second-worst offender after NTP.
It *created* the problems that those firewall rules were put in to
solve. Today if you want to make a DNS request whose response is
likely to be larger than 512 bytes, you're practically forced to do it
over TCP.
