Maintaining drivers out of tree requires a few hours of testing and maybe some minor changes every two months (and that's only if you for some reason want to keep up with the main release cycle, and not just with LTS releases). It certainly does not mean keeping up with 20 patches each hour. People spend more time walking their dog during a week, than they would maintaining the out of tree driver every few months, if they changed to that as a hobby.
