Yes, this is a goal of the API and the current design supports this via
"Verifiable Profiles" [1].

Essentially, a verifier website asks for a set of attributes from the
user and the user may -- via their credential repository or "digital
wallet" -- assemble a "profile" that contains these attributes, backed
by some appropriate set of credentials. This profile is then transmitted
to the verifier website to fulfill its request.
