ADDITIONAL INFORMATION

You must be using the Libinput driver on X11. This feature cannot be implemented for this use case due to lack of support in Libinput itself. See https://gitlab.freedesktop.org/xorg/driver/xf86-input-libinput/-/merge_requests/12

We have to wait for that issue to be fixed in Libinput before we can add the feature.

On Wayland the situation is different, and we have already implemented a scroll speed feature. Another alternative is to remove Libinput on X11 and use the older evdev drives, which do have this feature.
