Validate multiple subjects

Would it be possible to add a convenience validator method jwt.WithSubjects(subjects []string) that returns an error if the request's subject doesn't match any of the subjects?

I'm curious about the use case for checking against multiple subjects, since typically you'd have a JWT representing claims about one specific subject. Delegation?
