Touchpad gestures on PC

Touchpad gesture support for PC has been missing since forever, depite full support for Mac touch pads at least since I first started on photoshop back in 2008. They've implemented those same pan, rotate, zoom gestures for PC based touch screens, so why can't the exact same gestures be implemented for PC mouse touchpads? Many PCs have percision touchpads that are even better than the ones Macs use, and so many other apps have full PC touchpad gesture support, so why wont adobe impliment it already?
