I’m not sure how much visibility this has had to IETF wgs that aren’t in the IoT space, but FYI, the key thing to know about this proposal is that it’s not actually a router.   It’s a weird sort of bridge, using proxy ND to make it appear as if all the devices on the IoT network are actually on the conventional (ethernet or WiFi) LAN.   I’m not taking a position on whether this is a good or a bad idea, but since it’s in last call, I wanted people who haven’t been involved thus far to just notice what’s being proposed and think about it (and possibly review the document).
