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.

Shall we start having Apple certified power sockets now in case a dangerous socket misbehaves and fries your electronics?

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.

So, those power bricks... its got that neat "remove this and swap for other plug types" connector.

One of the other connectors is an extension cable. https://www.apple.com/shop/product/MK122LL/A/power-adapter-e...
