This is still the crux that I'm not really understanding. What exactly is light and heavy in this regard? To use a few examples that have been common in the discussion so far, if the demons and devils entries make a few references to the Blood War, and if in the dwarf entry it says that they were once enslaved to giants, how is this not a light touch? They're just throwaway references. They have no impact on play. If you don't want to use them, there's literally no implication to your game if you make the change.And 5e might still turn out to have a lighter touch than it seems so far.
Whereas, on the other hand, if my game rules say that dwarves gain a bonus against giants in combat, then I've got something that I actually have to either houserule or figure out how to accept in game. That, to me, is a heavier touch.
