does anyone believe that worldwide adoption of a "let's turn off UDP/ANY
for security reasons" would remove this capability from enough servers
in the policy's first 25 years to make any difference?

of such believers, do any also believe that the attackers will be unable
or unwilling to find an alternative query?

security economics tells us not to bother building defenses whose cost
is higher than the attackers' cost of evading them.
