Class 0 devices cannot very well be full citizens of the Internet (at least we tried to define the class so this is approximately true), but they indeed can have some connectedness to them. IPv6 beacons are one such example, but also maybe devices with local interconnects that talk to an IP node. Section 5.2 has class I0 for the latter. I0 devices may still terminate application protocols such as CoAP and security protocols (e.g., DCAF was designed so this is possible).
