If the sockets are right next to each other, couldn’t the interlock be entirely mechanical? Pushing a connector into one socket disconnects the DC from the other socket.
In China you see two plugs, but that's because one of them is for AC charging (China's gender-reversed Type 2 connector) and the other is for DC charging (China GB/T connector).
It's somewhat difficult and costly to put multiple DC charging sockets on a vehicle because you need additional high-voltage switches/relays and cabling. Each DC socket must be interlocked and isolated while the other is in use.
