I'm not sure how that hasn't been done already. They're running linux so the drivers and kernel changes should be covered by gpl.

The display driving code is part of their "xochitl" binary, which is not GPL (and might not be allowed to be, eink-the-company is rather protective of their tech and waveforms). ~All modding happens by reverse engineering the binary to call into that code, either to change behavior (rmhacks) or to act like a display driver for other software: https://github.com/ddvk/remarkable2-framebuffer
The rest has been released a few times, though last I checked it was quite out of date. Far from ideal, but still significantly better than most companies: https://developer.remarkable.com/
Their E-ink display driver is userspace unfortunately...
