Why is 'touch-events: pan' not a value?

[fantasai]

Seems like 'touch-events: pan-x pan-y' is possible, why isn't there a 'touch-events: pan' keyword? Is this combination discouraged for some reason?

[mustaqahmed]

If my guess is correct that you meant touch-action here (instead of touch-events), we have touch-action:manipulation to cover panning in all directions.

(In Chrome, touch-action:manipulation covers a bit more than that but it is beyond the scope of this spec!)

however, touch-action:manipulation also allows pinch-to-zoom, while touch-action:pan-x pan-y (or a potential touch-action:pan) does only allow the browser to do pure panning/scrolling.
