I gather that these fine UK educational establishments have read the
specifications and the discussions leading to it.
I understand the spec. I've not read the discussions leading to it, but if
there's a GOOD reason to assume every AAAA record (without a corresponding
MX record) points to a mail host, then I'd like to hear it.
BTW, are you suggesting that Internet Standards should be determined by
what Google does?

What I'm suggesting is that things currently permitted by standards might
not be permitted by local policy. I don't like the situation that a DNS
lookup can't tell me whether an email domain really is supposed to be
deliverable.
We get lots of mail "from" domains with "A" records and no MX records. It
turns out that many of these addresses are undeliverable, and life would be
much easier if that doesn't happen with AAAA records in future. I'm
inclined to adopt a local policy that requires an MX record in the absence
of an A record.
I cite Google as a large provider that can influence best practice. I'm NOT
suggesting their behaviour should set standards. But, if certain practices
are required to get mail delivered to Google, then they're likely to be
widely adopted.
