Dummy Smart Switches

I am starting with Zigbee based home automation using smart switches coupled with a physical switch. I will also use smart plug, Door sensors, vibration sensor, motion radar sensors etc. In normal case it is possible that someone switch off the light or smart plugs via physical switch and consequently impacting the zigbee mesh. Do you people place some dummy zigbee switches (1ch/2ch/4ch gangs) behind wall socket solely to act as Zigbee repeater ? I don’t like those usb sockets repeaters, those occupies wall socket space unnecessarily.
