Hi, At IETF 116 it was discussed to also register a code point for 48 bytes non-aggregate BLS12-381 signatures, which several people agreed with. I created an issue on GitHub.
https://github.com/tplooker/draft-ietf-cose-bls-key-representations/issues/21 I remembered this topic when I discussed with Christian Amsüss who said that 48 bytes COSE signatures might be exactly what he needs for Group OSCORE in some use cases.

Title : Barreto-Lynn-Scott Elliptic Curve Key Representations for JOSE and COSE Authors : Tobias Looker Michael B. Jones Filename : draft-ietf-cose-bls-key-representations-02.txt Pages : 23 Date : 2023-03-13 Abstract: This specification defines how to represent cryptographic keys for the pairing-friendly elliptic curves known as Barreto-Lynn-Scott (BLS), for use with the key representation formats of JSON Web Key (JWK) and COSE (COSE_Key).
