State of multitouch on the web with trackpads?

[unphased]

I am thinking about the best way to implement two-finger-scroll on a trackpad to freely move around in x and y within a scene in a canvas.

It seems that the only natural way to do this still is to make some kind of fake larger scrolling area within which to scroll like this, and then read out the scrolloffsets to apply to the actual real thing that we're scrolling.

This is obviously problematic in many ways, because the scrollbars aren't going to be showing anything sensible, and also this still doesn't address the default scroll-left-to-go-back gestures present in safari and chrome on macOS for example.

For a tablet the touch events APIs are available so this can be readily implemented for that.

Is this likely to change? With all of your expertise on touch events and browser events in general, do you know if something like opening up the touch events API (or something like it) to raw trackpad events is something on the web standards roadmap?

Thanks.
