I'm in the same boat. The thing is that I like the first half of the animation when it matches the speed to the keyboard gesture. The second half of the animation after you let go, the speed suddenly slows. It feels like an attempt to skeumorphically adapt those drawers you can't slam, that have an air cushion that blunts the momentum and have magnets to draw it the last few millimeters shut.

If I could just "slam" back and forth with the three finger gesture I would be happy. Nothing is going to break from slamming my workspace side to side, I don't need to be protected. Those last milliseconds of the animation, when keypresses still don't point to the target space, are really annoying. I would like to just remove the "air cushion"/modify the bezier defining it. I get how it's supposed to feel 'high end' but it's nonsensical in context and just gets in my way, even if it's in a tiny way.
