IETF logoThe new COSE working group charter includes this deliverable:

4. Define the algorithms needed for W3C Web Authentication for COSE using draft-jones-webauthn-cose-algorithms and draft-jones-webauthn-secp256k1 as a starting point (Informational).

I have written draft-jones-cose-additional-algorithms, which combines these starting points into a single draft, which registers these algorithms in the IANA COSE registries. When not already registered, this draft also registers these algorithms for use with JOSE in the IANA JOSE registries. I believe that this draft is ready for working group adoption to satisfy this deliverable.
