The hysteresis is a software feature that filters out small movements, stopping wobbly cursors when the finger rests on the touchpad. Not all touchpads need it, most of the modern ones do the filtering in the firmware already (or just have more accurate sensors).
We tried to remove it by default a year and a half ago and then had to play whack-a-mole with the touchpads that still required it. I've resisted adding a toggle for it because it's unclear what that toggle should really do. This time we use heuristics to disable it - if the touchpad doesn't send motion events with the finger stationary on the touchpad it's an indication that we don't need the hysteresis and can disable it. This vastly improves the reaction of the cursor for small movements, especially those changing directions frequently.
