As other IESG reviewers pointed out (better than my own description), having 2 non identical ways to encode the same information is going to cause interoperability problems. It also forces implementations to support both encodings and it makes draft-ietf-core-yang-cbor Normative.

I would encourage the WG to pick one mechanism. If it ends up being draft-ietf-core-yang-cbor, I am happy to progress it quick. (CORE WG is one of the WGs I am responsible for)

Best Regards,
Alexey
