That's actually untrue because for USB2 vs USB3 my computers already showed notifications that the USB2 cable is slower than necessary. The computer KNOWS the other device, it has a driver for it, and the driver can say "this device is capable of more".

Sometimes yes, other times it might be possible in another way, but a lot of drivers are generic and don't have an exhaustive list of all devices in existence. Devices only need to be identified as a certain (generic) type.

It's still certainly possible for a device to report it's capabilities and plenty of devices seem to correctly do it already.
