Unsurpisingly (with me being an author), I also support adoption.

Subject: Re: [COSE] Call for adoption of
draft-lundberg-cose-two-party-signing-algs-07
I (one of the authors) support adoption. This is a prerequisite we need for a
proposed WebAuthn extension for signing arbitrary
data<https://github.com/w3c/webauthn/wiki/Explainer:-WebAuthn-raw-signing-extension>,
which would use this to perform signing operations with keys held in a
WebAuthn authenticator. In particular, the COSE_Sign_Args structure is needed
for passing additional parameters needed to sign using a private key derived
using ARKG<https://datatracker.ietf.org/doc/draft-bradleylundberg-cfrg-arkg/>.
Thank you!
