I would suspect so for simpler sites. Passkeys have many sharp edges -- and sites want a memorable identifier -- which passkeys don't provide today. 

A WebAuthN interaction between the browser and the issuer as part of EVP I think provides a fantastic step up for simpler sites. The issuer knows the credentials it supports for the email address provided -- and the site gets a verified email and the security of passkeys without having to directly support passkeys. 

A browser integrated with an issuer can do the same thing to provide a directed email address to the site and use a passkey for authenticating the user transparent to the site as Sam mentions above.
