We have alg for ECDSA with the NIST curves P-256, P 384 and P-521. Are you wanting Specifically Bernstein's 25519 curve or some more general curve agility?
We restricted the curves initially in favour of getting interoperability as opposed to using arbitrary curves. It may be best to look to the CFRG for advice on specific curves. JOSE is mostly about the serialization. John B.
