I feel this is a side-effect of so many people getting "simple" wrong, as in, calling things simple because they superficially seem so, even while being aware of but ignoring the underlying complexities.
Completely agree. It's entirely about eliminating unnecessary distinctions, not about relative simplicity (which would need to be defined in context—we do not have a universal notion or measure of "simplicity" or complexity—any such notions we do have are domain dependent and usually observer dependent).
