The BS says these devices only provide "supplementary" protection they require upstream "Additional Protection" if Additional Protection is required. RCDs do not provide protection for upstream only downstream of the device. The unswitchef varaties do not in themselves provide satisfactory isolation. Yes you could isolate by removing the plug from the socket variety or remove the fuse from the SFCU variety which does put them in the catagory of a chocolate tea point.
Do you agree they are not suitable when Additional Protection is required?
