Although it is personal, at least one of its benefits presupposes someone else: the ability to guest someone (who has to fly the same flights as the SP cardholder) into the lounge. Allowing the travel companion (who, again, would have to fly the same flights as the SP cardholder) to go through fast track security would be a natural corollary of the previous benefit.
