The Paint Brush has its Erase Brush equivalent, but the Pixel Tool lacks its Erase Pixel counterpart. It would be more intuitive and useful to use the tip of my stylus to paint with the Pixel Tool and be able to quickly correct mistakes with the stylus eraser using a true Erase Pixel tool instead of the regular Erase Brush. There is an "Erase" alternate mode for the Pixel Tool that can be activated with Ctrl, but as far as I could see it cannot be bound to the stylus eraser.
Hopefully this would be easy to do. It would require no new functionality, just to elevate the "Erase" mode of the pixel tool to a tool of its own and make it usable like the Erase Brush.
