Seems the French have come up with a way of making their CEE 7/5 socket outlets totally flush.

There's a spring loaded plate on the front of the socket, which is pressed back as the plug is inserted.

The socket's also shuttered.

Looks like quite a decent design.

They're aiming it at areas that need to be dust free and wipe-down (with the power off) e.g. hospital rooms, kitchens, etc. But, I could see it catching on in homes purely for the convenience and looks.
