This draft does a good job of discussing typical home use scenarios, where the problems described in the document are most likely to occur. It might be worth noting that some of the assumptions about prefix stability may not be applicable to commercial IoT deployments. This is relevant because some IoT deployments make use of sleepy devices that may only wake up once per day or even less frequently. The suggested parameters would be inappropriate for such a device. At the same time such a device likely is not relying on RA, since it would not be awake for periodic refreshes. Nevertheless the operational mitigations section could use some additional verbiage about applicability so that readers do not assume that the advice given there is universally applicable.
