MvdScopeTransformer question

I noticed that the MvdScopeTransformer is very similar to the default EdcScopeToCriterionTransformer, with the exception of the list of knownCredentialTypes. In particular, if a scope string is not recognized as a "known credential" it returns the Criterion

"verifiableCredential.credential.credentialSubject.claims.level"=credentialType

The purpose of this fallback behavior is unclear to me. Does this relate to an MVD-specific scope alias, or is there another reason behind it? Why not return a failure if the scope is unrecognized?
