Endpoints MUST ignore unknown Setup Options as specified in Section 9.1.
New Setup Option types are registered using the Specification Required policy ([RFC8126], Section 4.6). Provisional registrations are permitted to allow experimentation and avoid codepoint collisions between independent implementations. There is no reserved range for private or application-specific use; implementations that need custom Setup Options SHOULD request a provisional registration.
