Changing Camera Zoom Factor

Hello, I am in need of a way to change the amount the camera zooms as a user uses pinch to zoom in a cesium viewer, such as on a mobile device (phone, tablet etc). Right now, the amount the camera zooms with pinch to zoom is way to slow for my use cases, and makes it frustrating to use. I saw there was a PR awhile back here: Expose camera controller zoom factor by brianpmaher · Pull Request #9145 · CesiumGS/cesium · GitHub that seemed to get closed. Is there any way this change can be made public?
