I was surprised to learn that Wayland still doesn't offer control of keyboard LEDs like Scroll Lock, so unprivileged programs that use those LEDs cannot be ported to Wayland.

Even if I didn't depend on such a program myself, I would find it strange that Wayland gives the compositor responsibility for only part of the keyboard: its keys, but not its indicator lights.

After all they started by locking down everything and then they are creating all the openings that real world programs need to do what people use computers for. It's probably a better approach that starting with everything open and attempting to lock down, but it takes a long time and some of us will be locked out by some hardware / software mismatch. In my case it seems that Noveau can't talk properly with the backlight control of my card. Neither X11 can with those new kernel and driver but at least it can use gamma correction to simulate a darker screen. Wayland does not have gamma correction or it doesn't work as it should, I can't remember.
