Most people don't use ipv6 multicast in anger (i.e. anything more than 
nd / bonjour / etc), so mld snooping isn't that important for small 
switches.

For proper device access control, you also need the ability for the 
switch to do ND/RA + DHCP snooping / filtering.  Otherwise you open 
yourself to rogue routers and/or address assignment.
