If you mean cables that have a USB-C tip at one end, that's true, but I could cite thousands of distinct cables that have a USB-A tip at one end.

Also "charge only" cables violate the spec, and thunderbolt-only cables violate the spec.

When the cable is USB-C at both ends, there are different speeds and that's pretty much the only thing you need to care about. Occasionally you need to check whether it's a 60 watt cable or something higher, but not often.
