Sure, the wall chargers you have in your house are. You think the 400V, 625A circuits (250kW chargers) are just dumb circuits though? Fairly certain they have temperature and voltage monitoring on both sides of the cable and both sides of the connector, all to monitor for any issues with either the connector or the cable continuously. Anything goes wrong, gets to hot, etc? It kills power. You're right though. Medium voltage circuits (and above) are going to be much more complex. The fact is, once you start operating at medium voltage and above, stuff that previously was an insulator may not actually be as insulating as you think...
