See https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings/issues/27 The Accessibility tab was made redundant with the implementation of the new playspace/room/universe tab in https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings/issues/60 The tab inherited from the PttController class, which required changes in order to work with the new IVRInput system. See https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings/issues/51 for more about the IVRInput system. Removing the page now at an early state is going to make it easier to refactor the PttController since only one class is inheriting it, instead of two. Since the Accessibility tab is going to be removed anyway, it makes sense to remove it now.
