/**
 * Read-only version of the SigningConfig wrapping another SigningConfig.
 *
 * In the variant API, it is important that the objects returned by the variants
 * are read-only.
 *
 * However, even though the API is defined to use the base interfaces as return
 * type (which all contain only getters), the dynamics of Groovy makes it easy to
 * actually use the setters of the implementation classes.
 *
 * This wrapper ensures that the returned instance is actually just a strict implementation
 * of the base interface and is read-only.
