My thinking is that it's just going back to the days when you drove the car with your foot and the car was a dumb analogue device that wasn't trying to learn and adapt around your past actions. It's one of the key criticisms I have of modem cars with drive by wire
Back in the cable throttle days, 100% pedal meant 100% throttle opening. It makes it jerky now because 25 or 30% pedal is 100% throttle opening, and its all done with the turbo wastegates and VVT at pedal positions higher than that.

I have tried this on my 135i M6, IJ rom, 190 load target with stock throttle. Can confirm that throttle is very touchy, especially from a stop and in 1st gear. Could probably learn to drive around it. Linear throttle feels too slow for me, I'll probably massage the throttle table to be a bit smoother though.
