	I was responsible for deploying such policies in the past, going back as
far as the UDP/1434 filters I was forced to deploy due to persistent network
congestion.  Rolling these back took some time.

	The same is true for UDP policers we ended up rolling out for NTP, chargen
and other activities.

	Extending these to consumer side where the traffic often originated makes
sense until the devices can be secured.  You can blame the providers for deploying
filters, or not disconnecting consumers that have devices that can be exploited
or whatever other reason you believe.

	As a network operator my goal was always to ensure customers receive
the traffic they expected, high rates of UDP were often not what they wanted.

	Adusting the limits may be useful but I still think the question of
what rate of UDP traffic is acceptable is a practical one for the future.
