  | I didn't see any other RTM_* consumers in our tree.

sbin/routed and usr.sbin/route6d are likely to benefit.

There are also a whole bunch of processes that write to the routing socket,
then read it, to verify that the message they sent was received - most of
those are essentially one-off uses (do something and exit, like sbin/route)
but a couple (rarpd ldpd - more? didn't see any, but...) are daemons and
might possibly benefit.
