I think the question is relevant.

On one hand, it's counterproductive to tell some computer to stop
sending, "protocol police" is making laugh.

On another hand, recent documents do have these kinds of semantics:
PIO-X, prefix-exclude option in DHCP, and others.

On the same vein, even for IPv6 there is need of such semantics: the
IPv6 DNS address in the RA gets installed on a Client forever.  And it's
that IPv6 Host that makes IPv6 noise on IPv4-only networks.
