Now, according to the report this aspect of the design appears to have been instituted because of potential failures of the AoA vanes at takeoff leading to a false stall warning - which would present a hazard close to the ground (this also means that the suggestion of adding WoW switch to the trigger inputs wouldn't work)
Adding a layer
At less than 60 knots ... even on takeoff .. you are on the ground not close to the ground .. so no hazard
And at 70 or 100 knots .. you are alway on the ground
Sorry but I don't understand the logic of this design ... (60 knots)
