*Still confused. In the real world, Company A never delegates to Company B.
Company A just operates a PEP. *

*The question of whether Company A delegates to the PDP or the Subject
delegates to Company A seems talmudic but maybe it's important to resolving
my confusion.*

*I agree with you that the PDP has no need to invoke the service so it
shouldn't have that permission but in the real world, the PDP can collude
with a service provider B out-of band and Company A would have no idea of
the collusion.*
