Heh, I feel intruded upon.
A list of gods belongs in a setting. Not in a Players Handbook. It can also be in the DMs Guide as an example within worldbuilding tools.
The Players Handbook can give different examples. "In Dark Sun, the prominent cosmic forces are the elements, Earth, Air, Fire, Water, and the planet Athas as a lifegiving whole. In Forgotten Realms, the prominent cosmic forces are gods inhabiting domains in the Astral Plane, each having a portfolio of different cosmic forces. In Eberron, cosmic forces vary by culture, each of which manifests miraculous power, despite conflictive points of view."
But that is it. Describe. Dont prescribe.
Avoid strong-arming any particular setting.
