I was always horrified by XDA solutions, and wondered how apparently so many people didn't find that scene incredibly sketchy and suspicious. And when more credible community open source models were already widely known.
I'd be very happy if PostmarketOS got more progress towards solid mainline kernel support for some devices -- including for the nascent 4G hard requirement of my carrier. (I tried to help a short while, but I can't currently. And I probably won't spend more time on it until I can be doing userland app and UI/UX development atop a solid foundation.)
