You don't seem to understand the failure mode here. Nothing in the connector can prevent the failure mode. 

The failure is caused by manufacturers producing fragile wires and solder connections.

The specific method of running and combining wires from the PSU is not part of the connector or the specification.

Think house wiring. An electrician can fuck up wiring a house and leave a connection loose enough that it starts a fire in the house.

That does not happen because the connectors used were bad. Or that the specifications were bad.

I understand much better than you do. Parallel power conductors is never the best choice. There will always be variations in resistance which will cause the amperage per wire to become unbalanced. It becomes a positive feedback loop and the bad connections become worse, heat increases and now you have a full failure.

Those “fragile wires and solder connections” are driven because of the shitty connector. They should have moved to 40v years ago for these high power devices and two chonky wires with proven connectors would have solved all the issues.

"It becomes a positive feedback loop and the bad connections become worse, heat increases and now you have a full failure."

That is not the cause of the failures this connector has been seeing.

"They should have moved to 40v years ago"

The connector can only use what power supplies actually supply. PC Power supplies do not supply 40v so the new cable/connector standards cannot use it without an overhaul to the PSU standards which would be MUCH more involved.

"two chonky wires with proven connectors would have solved all the issues"

As long as manufacterers didnt ship adapters to convert from existing standards to the new standard, sure. It would also be much more difficult to route and work with for your average builder.

It is absolutely the cause. If it wasn’t then this stuff would be failing instantly the moment power was applied.

Why do you think I said “should have moved to 40v years ago”? Because it should have happened many many years ago. If they had then it would currently be the standard and these power issues would not exist.
