The big issue is thunderbolt. Sometimes you'll have to explain to people that the external display can only be connected by this USB port using this cable and not that USB port using that cable. "But they look exactly the same". Yes they do :(

Isn’t that the fault of thunderbolt for overloading the same connector for a different protocol?

  USB3 does the same with alt mode supporting DisplayPort.

  And yet USB does 'too little' overloading of the USB-C port: > Full-featured USB-C cables that implement USB 3.1 Gen 2 can handle up to 10 Gbit/s data rate at full duplex. They are marked with a SuperSpeed+ (SuperSpeed 10 Gbit/s) logo. There are also cables which can carry only USB 2.0 with up to 480 Mbit/s data rate. There are USB-IF certification programs available for USB-C products and end users are recommended to use USB-IF certified cables.[12] * https://en.wikipedia.org/wiki/USB-C#Cables https://en.wikipedia.org/wiki/USB-C#Cables Power delivery has a minimum of 60W (3A@20V) with support up to 100W (5A@20V), with a recent addition of 240W (5A@48V): * https://en.wikipedia.org/wiki/USB_hardware#USB_power_delivery https://en.wikipedia.org/wiki/USB_hardware#USB_power_deliver... And "USB-C" is not a monolithic entity, given there have been several revisions now (1.1, 1.2, 1.3, 1.4, 2.0, and 2.1 in May 2021).
