I get your point after realizing that you make a distinction between
trigger and hint in your draft. The gain of doing reachability test
(with unicast RS/RA) in the case of weak hint could be less signaling
overhead, especially in the downlink, and less disruption to
routers/hosts. Consider that RS/RA exchange between hosts and routers is
changed from one-multiple-multiple to one-one-one.
