Devil's Advocate and EMC amateur I am. For both personal use and for test bench automation at the factory, the MB is chosen with attention to EMC emissions and immunity. So this stuff can be considered important to both residential and industrial end-users.
It is not unreasonable for the non-engineer end user to expect that the mb will not require installation in a steel vault with a beryllium gasket around the cover and not be subject to total destruction from a minor ESD event.
