UBports is pretty close: https://ubports.com/ https://ubports.com/ It uses libhybris, so they're limited to the original kernel or something close to it because of proprietary drivers. But it's a community project since Canonical stopped Ubuntu Touch development, and it's had a desktop mode like this for years! The PostmarketOS project is similar, with an explicit goal of mainline support where possible: https://postmarketos.org/ https://postmarketos.org/ But yes, I would be much happier if devices had support in the mainline kernel and could run any distro you wanted right out of the box. (And some devices just straight up lock you out - I try to avoid those whenever possible.)
