  The touchpad's libinput backend is only for wayland. And it also has some different code to support xf86-input-libinput under its x11 directory. As I said before they are different things.
  
  We haven't get to the point to support wayland in this kcm yet.
  
  If people has better idea about the naming we can change later.. right now, we seems to use pointer acceleration for "rate". The profile is more clear.
  
  Also if you check the Mouse navigation tab there's another "acceleration profile". I guess that's somewhat matching in the meaning.
