I think it adds another layer. It maintains the “Light is still mostly good, and Void is still mostly evil” vibes", because of the way those forces interact with our characters’ physiologies and psychologies.
And that remains largely true. It basically turns the forces into these amorphous gods, these sentient wills, and we’re just tapping from their power. For example, if you read the wiki on Light or Void, it says that the forces are Light and Void, but they manifest as Holy or Shadow magic. I think that distinction is important, because it explains how the Forces can have their own agenda without necessarily superimposing that on its users. The users of that magic likely align with its morality, but that doesn’t necessarily have to be the case. That degree of freedom allows us to make varied characters without necessarily restricting them to the same code of the Forces they wield.
