It depends on whether the router is also the wifi access point. In general,
in the large wifi networks to which this draft is targeted, that is not the

the network administrator knew that a particular interface was providing
service to a network with a large number of mobile nodes, then the
administrator could configure that interface to send solicited RAs unicast.
