"(Actually, since Airbus hides in fact the entire THS from the pilot, if the pilot is made aware of a THS movement it is necessarily a surprise)"
The THS is not "hidden"; the trim wheels either side of the thrust lever quadrant clearly show any THS movement. Auto trim would not be a surprise to a properly trained Airbus FBW pilot.

Mechanically coupled side-sticks would need to have joints, bearings, levers etc, and would require a mechanism to uncouple the sticks, all of which could jam and cause more problems than it might solve.

Hence, if the side-stick position indication display - see below - that we use to check our controls before take-off were to reappear on both PFDs in the event of a stick being held at or near a limit in flight, then both pilots - and a third pilot - would be able to see on both PFDs what was happening. It would only take a couple of lines of extra program code in the software to add this feature.
