Could we have a "direct parent" check rather than going up lots of levels?
No.
Eg, if you are having to fall back to an A record, look at the
direct parent for a TXT record with appropriate data in
You have _no reason_ whatever to suppose that the parent is the
appropriate place to ask this. Indeed, you don't even have a reason
to suppose that the parent isn't part of the same zone delegation
you're looking at (where's the SOA? And why does the SOA tell you
anything anyway, since organizations can cheerfully introduce zone
cuts for administrative purposes that have nothing to do with
delegating outside the controlling organization).
It could be worth logging how many times we have to fall back to an
A/AAAA record, AND the delivery succeeds - I may have a go at that
ourselves.
That would indeed be useful empirical evidence.
Best,
