I’ll join this bikeshed:

+1 to identifier_type.

> Introduced some normative requirements around the use of both `sub` and `sub_id` in the same JWT: "implementations MUST NOT rely on both claims to determine the subject,” though falling back to one if the other isn’t understood (e.g., sub_id has an unknown subject identifier type) is allowed.
> Added security considerations. Interested in feedback on this. The security considerations really depend on the context in which subject identifiers are used, so I’m trying to strike a balance between referencing likely relevant considerations and providing useful information without copying in a bunch of content that may or may not apply.

>   Security Event Token (SET), and a registry for defining and
>   allocating names for these claim sets.
