Just turn off the SMTP listener. This functionally identical to a
4.X.X reject and saves resources on both client and server.

Only if this is documented. The soft_bounce parameter is listed on
the postscreen(8) manpage, this is perhaps a sufficient promise to
match user expectations and so I would expect it to work.
This said, it is far simpler to turn off SMTP service.
# postconf -e 'master_service_disable = inet'
# postfix reload
with appropriate adjustments if the target is a non-default instance.
