You would need an AWFUL lot of hosts for this to add up to a few 100pps (or even 10pps) of multicast traffic.
You're missing the point... most WAPs are horrible with multicast. It doesn't matter if it's v4 or v6, at L2, multicast is multicast.
At 100pps the WAP disappears from the network. "It's dead, Jim!" In many cases, a single multicast packet is enough to disrupt traffic flow as the AP stops to fire the multicast frame, individually, at each associated peer.
As others have pointed out, IPv6 uses multicast all over the place. DHCPv6 is just one of many sources.
All we're saying is DHCPv6 should be like DHCPv4... have a backoff period and eventually give up entirely. (yes, there are v4 agents that continue to try, i.e. restart every 5min, etc.)
