It is a connector. None of the connectors inside a PC have those. They could add them to the circuitry on the PCB side of the connector, but that is entirely separate from the connector.
That said, the industry seems to be moving to adding detection into the PSU, given seasonic’s announcement:
Finally, I think there is a simpler solution, which is to change the cable to use two large gauge wires instead of 12 individual ones to carry current. That would eliminate the need for balancing the wires in the first place.
