Oh, look at that. Thanks.

Hello John,
https://tools.ietf.org/html/rfc7489#section-6.1 say
.. MUST

As you surmise, that won't work. For one thing _dmarc.*.gov.uk isn't
a wildcard, and for another, *.gov.uk only
Dunno if this ever came up before. What, if anything, does this mean?
_dmarc.example.com IN TXT "v=DMARC1; p=none"
_dmarc.example.com IN TXT "v=DMARC1; p=reject"
Looking through RFC 7489 I don't see anywhere that it says that more
than one record is forbidden.
For that matter, what if anything
