You're roughly right about the two ends, but what about the middle? It is absolutely possible for a high power supply to be connected to a high power sink (like an iPhone) via a non-compliant cable. A high current value is negotiated, the iPhone starts drawing that much current and then the cable gets hot and in the extreme case - starts a fire.

  You know how Apple has those ridiculously sized power bricks that make it very difficult to use standard power strips with? I once had someone tell me that normal power strips had their ground faced horizontally, and that it was 'unusual' for me to have the vertical power strips (which are nearly unbiquitous, as far as I can tell) - that was their reasoning on why Apples massive bricks posed no issue for power strips.

One of the other connectors is an extension cable. https://www.apple.com/shop/product/MK122LL/A/power-adapter-extension-cable https://www.apple.com/shop/product/MK122LL/A/power-adapter-e... Works very nicely with power strips and conferences where the power plugs are way over there.
