I'm not convinced that employing 3D Touch to do the typical things of mouse hover is a good idea. Displaying help text to users being lost when they do a very specific gesture? It needs to be something that every user can immediately pick up on.
Maybe a stare-o-recognizer using the camera? If the user looks puzzled at a button, display text to explain ;-).
