There's no need for me to define it: I intentionally did not word my

NOT use p=reject and why... and, as I said in my response to Scott, I'm
happy to add an explicit statement that it's an issue of interoperability
with existing, decades-old mail flows.
Does that mean that instead of "non-transactional mail flows" we could say
"mail flows involving decades old software"?

I'm very much against text such as this, as I think it encourages
deployments that are contrary to interoperability and to the intent of
p=reject.
I contend that p=reject (as with the similar construct in the older ADSP)
was intended for high-value domains and transactional mail, and that it was
never intended for use in domains where general users send general email.
I stand by the MUST NOT that I proposed.
I wonder if perhaps you might define "high-value domains" or restate your
position using a term other than "value" and its derivatives?
The reason I ask this is because your contention could perhaps be read as
"low-value domains MUST NOT use p=reject because their mail won't get to
its destination" and that seemingly ascribes a value to their mail that
might be considered somewhat higher than "low" in the eyes of some
beholders.
