It should be possible to receive a credential from an openid4vc issuer that also offers unsupported formats

E.g. I get an offer for sd-jwt and mdoc. I should be able to only request the sd-jwt cred, but currently it just crashes saying unsupported format. The logic is quite easy, but the types are now all typed as if it can't be an unknown format. So that would have to change.
