Understood, but if that displacement is calculated then you could be misled if the input to those calculations (whether electro-mechanical or digital) is outside of the specified range.
B777 and B787 have a large red switch to turn the FBW computers off and enable the pilot to simply fly like like a 707, 737, 757 etc. Airbus don't fit a similar switch.
No, as you know they have Direct Law, in which the computers simply translate the control inputs to flight surface deflections. While this arrangement doesn't have tactile feedback, it does take the computations out of the equation.
