Such side effect conflicts with the recommendation documented in Section 6 of [RFC7051]. NEW: Note that it was tempting to define three distinct DHCPv6 options, but that approach was not adopted because it has a side effect: the specification of a DHCPv6 option that could be used to discover unicast PREFIX64s in environments where multicast is not enabled. Such side effect conflicts with the recommendation documented in Section 6 of [RFC7051].
