I can't totally answer your question but I do know that the A320's Fly-by-wire Flight Control system has an Active Aileron function designed into it (originally pioneered on the Lockheed L1011-500). This is designed to move the ailerons to alleviate wing bending induced by turbulence, gusts etc and thus allowed the use of lighter wing spars in comparison to non load alleviation wings.
Although the A320 wings may not move as much as the B73H wings, the ride may be similar.
