I implement enough COSE (Sign1 only) to do RFC8366/Constrained-Vouchers at:
   https://github.com/AnimaGUS-minerva/ChariWTs

I also use https://github.com/AnimaGUS-minerva/cbor-rust
from https://github.com/franziskuskiefer/cbor-rust (Mozilla).

I think that you'll find that COSE is rather a swiss-army-knife kit, and that
many users will implement (and test) what they need, and leave the rest
aside.
Given the constrained focus of COSE, you may never see an all-singing library.

Also, the way in which COSE integrates with CBOR libraries probably depends
heavily on exactly how the data will be used.
