All fine and good, and I understand the desire to promote DNSSEC. This
argument is absolutely valid.

But still... it is only half the truth in my opinion.

For the sake of proper expectation management, the statement would have
been more accurate if there was also explicitely stated that DNSSEC
would not have helped enough in this particular case, just as was done
with the remark about the use of RPKI. A bogus answer is still bogus and
won't bring you where you want to go. Whether is is authenticated or not.

Until validating resolvers will retry at a completely other name server
in such a case, in order to try to fix wat is broken, DNSSEC just allows
you to discover that you have been fubared. Nothing more, nothing less.
