Since we know the whole heavens and hells thing does not apply to mortals as we just return to the aetherial sea, what do the gods do? They are seen as being tied to elements and they reflect that like any primal would. But they have been MIA for a very long time. They don't appear to be needed to maintain balance of anything in nature.

They could just be very powerful entities, but that seems narratively boring if there is nothing more to them than that.

If they have no say over souls or the state of the world their value as religious entities is practically non existent. We have not needed them before now. They were incapable of doing anything about the final days.

To paraphrase a certain Black Wolf, Just what good are these gods?
