Flight control surface deflection however serves no purpose as pilots do not control the flight controls surfaces themselves, except in direct law. The pilot controls the flight path (g-load and roll rate demand) and the FBW does what it needs to follow those demands.
Control surface feedback would be counter productive therefore, except if the bus would be reconfigured to fly in direct law all the time, by which time it is absolutely useless to have the FBW in the first place.
Now, a feedback of the stick position of the other pilot would serve a purpose.
