It is really worse. I have ton of USB-C cables doesn’t transfer data from flash lights, a lot of USB 2.0 speed cables with USB-C connector, then USB 3.0 cables rated at 5G/10Gbps without an easy way to know the difference, then Thunderbolt 3 / 4 cables one each.

Besides Thunderbolt cables, there is not a standard nor universal way to identity them. I had to test each cable by plug in an SSD then speed test the SSD.

Flash back 15 years, a cable with MicroUSB either transfer data, or not. The difference between high speed / super speed only lives in the device.
