    Whether this key needs a specific ID when it is in a Keyset.
    Tink Keyset derivation always copies the ID of a key to the derived key. Hence,a KeyDerivationKey needs a specific ID if and only if the derived key needs a specific ID, and so this is always equal to getDerivedParameters().hasIdRequirement().
