So on iOS 10 on an iPhone 6S, you can clear all notifications by using 3D touch to press on the clear button. You can achieve the same effect on an iPad Pro by using the Apple Pencil to apply pressure on the clear button instead. Instead of recognizing force from the display, the iPad recognizes force from the Pencil and does the same thing as it would on an iPhone 6S.
Neat attention to detail from Apple!
