The switch then knows what listeners are where, so when for example an NS is sent to the solicited node multicast address of a target during ND, the switch can send it only to those hosts it knows are listeners on that group.
Okay, so then to answer my own question from earlier, the answer is actually that an MLD is sent when an interface configures a new address to join the appropriate solicited node multicast group. It seems that, then, MLD snooping is valuable as it will prevent DAD and other ND traffic from using bandwidth towards hosts not in that group.
Other than solicited node multicast, is MLD used anywhere else in a network that does not have layer 3 multicast enabled on a router?
