The problem then is that the religion ends up entirely constrained by the founder; that's not going to help people engage with religion.
One problem I have with religion with a large amount of lore on the wiki is that I feel I may end up having to read all of it, then simply apply it as it already defines everything. Simple religions, on the other hand, allow more IC arguing about the religion itself. It ends up being defined over time, and evolving as the characters change.
