I agree. Not following the rules of engagement for stratum 1/2 servers can mean you block all NTP traffic from those nodes or issuing occasional KOD packets to those nodes. It is also possible a vendor thought it would be a great idea to hardcode some NTP server addresses in their routers and switches. We've also see that happen too.
