Can we make a standard zooming event?

It seems that there is no standard way to catch touchpad pinch-to-zoom event. Currently Chrome hacks with mouse wheel event with ctrlKey=true, Safari and Edge has their own GestureEvent implementation. Can we make a standard way to do this so that implementing zoomable element can be simpler?

Could you clarify what touchpad pinch-to-zoom does? Is it the same as pressing Ctrl + +?

Pinch-to-zoom with touchpads works same as pinch-to-zoom with touch screens, but with no touch points.
