My reMarkable is still stuck on a super old version (v3.3 I think), precisely because of xochitl being closed source and there's no stable and efficient way of driving the display. It's super sad because I would love to have much more things appearing on my tablet yet I cannot develop reMarkable apps easily. I'm not talking about browsers, but more like my Linear TODO list, calendar, etc., so I don't have to reach for my phone.

I really want to try for further reverse engineering of xochitl now that I've heard those AI tools have gotten so good at doing it.

Man I really wish one day I could run mainline Linux kernel on this tablet with the display just works.
