not all clients acknowledge a network's right to do such things at all
times. And of course it would be useful to tell the difference between
policy and a RST injection attack.

If the client does acknowledge the network has the right to set policy -
then the policy can be set on the client using existing configuration
mechanisms that allow the client to differentiate between authorized
configuration and perhaps less-authorized folks identifying their DNS
traffic. This is well worn ground in the HTTP space.
