A lot of them should. An inordinate amount of machines sit there burning power for no reason. You can argue that S3 isn't needed -- that nohz + C3/C4 + turning off the screen would be enough, and that might be legit. Heck, I'm constantly frustrated by every distro upgrade breaking power management for my monitor.
