Yeah, Permissions were sort of a midway point on the way to our final, blanket ruling on qualifying for powers. Permissions were a fancy way of indicating which character types qualified for which powers, which we then generalized to, "they have to clearly derive from your high concept aspect, whatever it is". And then we solidified the templates and types to provide more guidance.
The idea being, it has to logically track. So, if I'm an Emissary of Loki, the trickster god, probably I could see my way into illusion-based sponsored magic or glamours, any powers that help me with deception, and that kind of stuff. But Mythic Toughness probably isn't going to happen.
