We are the ones trying to make SLAAC stateful, contributing to IPv6 automatic configuration complexity, and apparent lack of coherence with respect to which protocol supports both, and why we e.g. disregard the work of other WGs (e.g. dhc). If you want to *partially* duplicate functionality in another protocol, please provide a rationale, or don't. > They are designing > their network and know their requirements best.
