This is currently a transition mechanism as we move pointer handling from direct handlers to a structured gesture system. This will be the preferred mechanism for handling nearly all pointer input.

Gestures are a unified way to handle pointer input from the user. They coordinate their activation and can resolve exclusions and priorities, ensuring the correct gesture is handled.

Though the Gesture system is still considered experimental it is the preferred way of handling pointer input now. The API is relatively stable, but small adjustments might be made to handle more complex gestures.
