Pen tilt support

I’ve made really great use of existing pen pressure support so far! Could there be additional support for pen tilt? Pen tilt support would make it much easier to paint full-screen pixel illustrations or other difficult subjects like a cloudy sky if I can control both size and gradient. I’m aware that what I’m doing is well outside of pixel art’s strengths as a pixel pusher of ten years but I’m willing to explore its boundaries.

Or, is functionality currently possible with the right extensions?
