I'm wondering if that speculation stems from the 1993 LH A320 accident at Warsaw, where the WoW timing was not sufficient to allow deployment of spoilers:

In response to that, Airbus reduced the required pressure on the WoW sensors, but they never abandoned it as a systems input.
That of course is a totally different application. For the record (I don't want to introduce another thread drift) it wasn't that WOW timing was adrift.Rather it was that the aircraft touched down so fast that even when derotated there was so much residual lift with full flaps that there was not enough weight on the wheels to overcome the breakout friction and allow the WOW microswitches to 'make' AI did introduce a software modification as a result but I cannot remember the details.
