Exactly! I find it amazing how many people talk about the USB standard like it is a single definitive standard, without realizing how non-standard it actually is, even within a single generation. I have several different USB-C cables, each with a different combination of signalling rate and PD levels. It is great that they have consolidated different cable specifications and have a single connector, but the various protocols take that simplification and suddenly turn it into something even more complicated. It is great that everything “pretty much” works, but weird when you throw in something like a VR headset that requires a higher transfer speed, find the correct cable, and then realize you’ve been getting a lower than top speed for everything else up to that point. I tend to follow this stuff, so I knew what I was getting into, but I was still surprised that I found myself experimenting more than I expected to find the correct cable. It could be a single standard with Thunderbolt cable as the standard for USB-C, but it is overkill for most things, so almost no one would want to pay the extra cost.
