I think everyone has a slightly different opinion. My thought is that anyone and aything, even the gods, who doesn't add something specific to Diana's personal journey drags the movie down. So in my view the only gods that even bear mentioning are Ares (villain) Aphrodite (only if she's the Patron of the Amazons) and Zeus (especially if they go the demigoddess route). Everyone else is impersonal to Diana, so they should be ignored, imho.
This is true of most movies. Anyone who is just there to be there is going to drag the movie. The individual gods are only worth mentioning if they serve a purpose
