Really?  I read the NOTIFY RFC (1996) so that if the MNAME name
server is included in the NS set, it will by default be excluded
from receiving NOTIFY messages from the other name servers when
they reload the zone, ref. the definition of "Notify set" in RFC
1996.  Unsurprisingly, BIND has code to do this:

        result = dns_name_dup(&soa.origin, zone->mctx, &master);
...
        /*
         * Process NS RRset to generate notifies.
         */
...
                /*
                 * Don't notify the master server unless explicitly
                 * configured to do so.
                 */
                if (!DNS_ZONE_OPTION(zone, DNS_ZONEOPT_NOTIFYTOSOA) &&
                    dns_name_compare(&master, &ns.name) == 0) {
                        result = dns_rdataset_next(&nsrdset);
                        continue;
                }
