It is currently not entirely clear what this subsystem entails, but at the very least it provides event notifications for when the keyboard cover on the Surface Pro X and Surface Pro 8 have been detached or re-attached, as well as the state that the keyboard cover is currently in (e.g. folded-back, folded laptop-like, closed, etc.).
