If at all, it will only create even more visual artifacts due to greatly reduced colour resolution for nearly-transparent pixels. The point of not using premultiplied alpha is freedom to change and edit your images, similar to providing 12, 16 or more bits per colour component. Using 8 bits (or using premulitplied alpha) is simply a performance issue, NOTHING else.
