Thank you! I most certainly did not grasp that until just this moment.

I wish that both of the above statements and/or the general concept
of the one-to-one correlation between running policy daemon instances
and incoming SMTP sessions had been noted at the very top of the
SMTPD_POLICY_README document.
That would have prevented a lot of confusion on my part.

I think that you just utterly negated what Wietse just got done telling
me, i.e. that $max_use and the number of individual requests sent to a
given policy server are not at all related to one another.
Did I misconstrue him, or have I instead misconstrued you?
Is $max_use a limit that applies to the count of individual policy
server *requests* or not?
