MLD Snooping only seems important to me if you are actually going to do
multicast outside of the local broadcast domain, which I can't imagine
doing in most service provider environments. Am I missing a reason for it
or a use case otherwise?

It would seem to me that either a wifi vendor would support source address
shield for IPv6, which MUST include multiple addresses, or it would just
pass everything without paying attention to source addresses. Is there a
vendor that does not do one or the other? If so, please name names.

Nice. Can you confirm if they've added DHCPv6 shield too? Source address
shield for IPv6?

Thanks, that's a useful data point.
