Do folks in the WG think there'd be utility in having a way to identity the
finger/thumbprint of a key in the cnf claim. A presenter might, for
example, present the JWT along with a public JWK and some
proof-of-possession of that JWK.  And the JWK would be bound to the JWT via
the thumbprint, which is more space efficient (with respect to the JWT
anyway) than the full JWK.
