Hi DozyWannabe,
I know you and others perceive the feedback loop as essential, but I'm not sure it is as essential as you believe it is when an airliner's flight surfaces are fully-hydraulic.
It doesn't matter that the flight surfaces are powered, it's more about being kept in the loop. e.g.
I can see the total fuel on board constantly, but the individual fuel tank gauges out of view, (they are on a systems page) so I get a warning when one tank is low, or an imbalance is building.

With the flight controls, I don't get any warning that I'm approaching maximum deflection with aileron or elevator, (or that the stab trim has run beyond it's normal range automatically). If I don't get that feed back through the side stick - then it would be nice to receive a warning somehow.

If AF 447 had some such warning, then I bet the Capt. would have been better able to diagnose their problem.
