Have you seen the list of safety features on UK plugs and sockets? The sockets have shutters in them that prevents anything being inserted into the live or neutral sockets unless the (longer) earth pin of a matching plug is inserted first.
Having said that, I agree: seems to be a belt-and-braces approach. No downsides.
And it allows you to cut power to an appliance without having to remove the plug.
Isn’t the USA 2 pin for many outlets, though. So there is no earthing. The uk socket requires the earth connection to be made by the longer earth pin on the plug before the flaps will open.
I don’t get how that makes it safer.
So when the dumb person tries to insert a fork in the plug, they don’t die electrocuted.

Sockets with flaps are code in the us too and have been for a while.

yes but you have to open both shutters at the same time. The ground doesn’t have a shutter.
