This kinda goes to my point. The USB 2.0 controller is absolutely not necessary for 99.99999% of all systems. USB 2.0 mice and keyboards don't need it, but work just fine on USB 3.0 and with a single controller able to address 127 devices, the USB 2.0 controller is a waste of money, components and motherboard real estate.
USB 3.1 and 3.2?!? The USB 4.0 spec. was finalized last August. 40Gbit USB.
