In my biased opinion USB 2 fallback is a misfeature. Most devices that use USB 3 for a good reason do terrible things when run at USB 2 speed, and it requires expertise to figure out why things aren't going the way they're supposed to.
On the other hand a mouse and keyboard will work pretty much the same...

- vlovich123 5y agoThe main problem I’ve observed with fallback is that 3.0 devices plugged into 3.0 ports sometimes get detected as 2.0 devices. Sometimes there’s a spontaneous port disconnect and the reenumeration causes it to be detected as USB2.0. If I recall correctly this was primarily only happening with a non-standard optical repeater cable so it could be the cable was doing something unexpected (eg 3.0 enumeration was taking longer than some timeout and it was going into 2.0 mode). In general though users preferred functionality, even if performance was reduced.
