This moves the problem though.

In the original example, RCD/circuit protection is regulated on the _property_ side, e.g UK has EICR for electrical install. Once its done for a property, its good until next inspection (in theory)

This moves the protection to the _appliance_ , which while it needs to meet certification, is much harder to police a consumer electronic device, than a physical unmovable premise.

I think these are great, but there will inevitably be devices that don't implement the spec correctly that still get sold to willful or unwillful consumers that result in danger to everyone.
