With a little bit of tweaking you can do it without layers. It's just more confusing (until you get used to it).

Sure you can build everything into a single material. Layers, when implemented correctly are just more versatile. It is a material that you can slap on and take off rather than go editing the face shader. Same as with the traditional lip material zone but without the hard edge.
