It's not at all logically hard to meet that arbitrary requirement,
you just need a zone cut everywhere you have a MX record. I've run a
DNS and mail hosting environment that way. Zone files are very small
and numerous. *Logistically* changing an existing zone with many MXs
for subdomains to that model could be a serious chore.
I question the veracity of "need a zone cut everywhere you have an MX
record".
My current working understanding is "you need a zone cut for domains
immediately subordinate of the PSL".
Right. I was speaking more directly to the OP's situation where they
already have a big zone rooted at a PSL-listed domain and a lot of
subdomains.
