You don’t need to follow the entire spec for a usb c. Usb c has a display port mode, but most laptops that have this won’t have it on every port. Most usb c cables also don’t support display port mode, which is annoying because they usually won’t say if it supports it.
Usb c extension cords are not allowed in the spec and yet they exist

It doesn’t need all that. All the complexity is because of stuff that’s been added to the spec. 500ma@5v will just work if all you only connect is + & -
