There have long been 2 camps in CORE WG on this -- 1 that thinks YANG data
modeling
should be used in IoT and another that thinks YANG data modeling is overkill
and not needed for IoT.  If YANG is used then SENML info is redundant.

YANG automation is about the entire tool chain, not just the bytes on the
wire,
but even if you focus just on that, I think CBOR+SID can achieve much higher
information density than SENML.

I do not think it helps to classify a router as an IoT device.
