I didn't know that loops are a problem in authoritatives,
and can't even imagine why. Can you give me a pointer to
the comments and proposals about this? I would think that
cyclic structures are never a problem if idempotence ensures
that updates won't cycle indefinately: "Oh yeah, I've already
seen that SOA serial number, I'll ignore it."

Yes, I was a bit rough; I should have said
nsdc update #possibly
ci -l "$ZONE"
zonec -v -c /path/to/nsd.conf -z "$ZONE" -o "$ZONE"
As you said, this would indeed work to edit a file, even
if it has request-xfr: settings as well.
I'm pretty impressed that the structures in NSD are so
general, and clean, that they would allow this approach.
Clearly, I must weigh if there is a chance that NSD would
ever ban this approach before adopting it in my infra.
