> There is no point to connector standardization if any cable can't do any function.
I completely disagree.
When the only difference between cables is max speed, that's still a huge improvement over a nest of different cable types, half of which are custom. And it's easy to get into a position where all your USB-C cables differ only by max speed.
Which is worse because they all look sort of the same, but they are not the same.
It's even worse for non-techies, who don't understand what a gbps or a watt is, and who will leave a 1-star review, or worse, trash their cable, because their cable was "slow" but was meant for 240W PD but only supported USB 2.0. They purchased it initially because it had 5 stars.
Ideally, there should only be "5 star" USB cables, and they should all work for all purposes that they can physically plug into.
The situation in the early 2000s is I could spot the cable I needed from a mile away.
