I wanted to respond to this comment in a bit more detail as I feel it might be getting to the heart of the matter in some our different perspectives. What you are describing in the above I would call setting lore, not cosmology. Though they can be related, they are not the same thing IMO.Contrariwise, in the World Axis, souls have an afterlife domain they're supposed to go to, based on whichever god they worshipped or were most similar to in their behavior, but the shattering of the Lattice of Heaven broke this connection, ensuring that some souls simply don't have an afterlife to go to, a problem most deities (regardless of alignment!) are content to completely ignore because they think they have bigger fish to fry. (One of my favorite things about 4e Bahamut is that he is the only deity who cares enough about the homeless petitioners of the Astral Plane, regardless of their alignment, to try to build for them a safe and comfortable home.)
For example, I use a modified version of the 5e great wheel. However, I really like the 4e lore and adopted, among other things, the breaking of the Lattice of Heaven. That lore works perfectly well in the great wheel setting and functions pretty much the same in 5e as it did in 4e. That is lore, not cosmology IMO.
PS - I do love that about Bahamut as well. 4e really had some of the best lore IMO.
