Anything keeping this from going official, it seems to be fully working?
Would also love to know an answer, or theory, to this.
Edit: more or less answered through some reading of the lineage page.
To go official, devs must commit to keeping the device supported (among other requirements) which is probably not something too many folks with the skills can or want to do. It takes a village I'd imagine for great support and that's why lineage is picky about official support.
That said, this port is really solid; I'd love to contribute to the "unofficial" cause. If you need or want help updating this @LuK1337 please let me/us know.
