Typical from bureaucrats who understand nothing about electricity !!
If that happened most fridges will burn out because of stalling motors, also bigger machinery will be affected as large compressors require the correct voltage to avoid crawling of the motors at 1/7 of the speed and have an early burn out of the windings. ( V² / R ).
Heating appliances will take longer to do the same job and lightbulbs will be a little duller but will last longer.
Harmonisation is a joke anyway. What about all the different plugs and sockets ?
Nothing wrong with an appliance with a multitap transformer and a voltage caroussel to select the correct value and a SMPS has a wide range, usually from 170 - 270 Volts ac.
My $ 0.02 worth.
