Hello, Ted,
Thanks a lot for your comments (past and present ;-) )! In-line....

Reviewer: Ted Lemon Review result: Ready with Nits
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.
Could you please elaborate a bit more?
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.
Just me double-checking: Do you mean it would be to short for them?
Please note that the default router lifetime is 1800 seconds. So a host
that sleeps for longer than that will presumably not have a default
router when it wakes up, and would need to do a "refresh" procedure
(RS/RA exchange) before it would be able to send a packet, anyway.
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.
Please clarify the above, and based on that, we could craft some text if
necessary.
Thanks!
Cheers,
