From my understanding of the way the android OS works, alternative OSs can’t really just become there on OSs because the would essentially have to replace the entire Linux kernel that Google currently uses, and no phone manufacturer as far as I know releases the drivers for their peripherals either. The first part I think would in theory be solvable, the latter would take a change in the way the phone ecosystem operates. Realistically for the latter to happen, I think we would essentially have to see certain phone manufacturers pop up who are willing to basically create an open platform with a driver offering and that would have to be the target.
