Description
The pointerevents spec provides a unified input model for handling pointing devices regardless of their type (e.g. mouse, touch, stylus) and contains many new capabilities to these events such as predicted points and pointer capture.

Rationale
The pointerevents spec is where new input features are arriving and developers using pointerevents instead of mouse or touch event listeners improves usability across input modalities. Additionally, using touch-action and passive event listeners improves scrolling performance. However, differences in behavior can lead to adoption or usability issues.
