+1. Avoiding a small amount of extra multicast traffic in these unusual
situations (misconfiguration, rollback) doesn't seem worth complicating the
implementation and increasing the risk of implementation bugs.

If the network has really serious problems with these packets (e.g., DHCPv6
server catches fire when it receives them) then relying on implementations
not to send them doesn't seem like a good strategy anyway.
