Rare insults

EU plugs designed in the past 50 years also have half-exposed pins and EU sockets from the past 30 years also have little rubber flaps that only open if they're pressed both at the same time (I've tried it, it works really well, I couldn't get a singular multimeter prong in my outlet until I used the second prong). There are no exposed live conductors anywhere in my house.

Nowadays the main practical difference between EU and UK plugs is the "lack" of a fuse, except any semi-modern appliance that could make use of a fuse should include one internally. In every other situation circuit breakers work fine, UK plugs have fuses because they historically couldn't rely on the circuit breaker existing.

Nowadays the regulatory focus is not on plugs, which are fine, but on GFCI. Gotta put one 30 mA differential per electrical circuit in kitchens/bathrooms and a whole house 300 mA differential. That's a much safer way to detect electrocution than wait until several amps have been going through the plug because all you're getting by the time the fuse trips is a fried person sandwich.
