It is also expected to cover USB 2.0 as well as 3.0.

It is a wait and see yet, whether industry will take it on-board although using it on WiFi for continuous application is a bit concerning, due to latency issue. WiFi is also not guaranteed connection as it tries 16 packets or there abouts and will give up. There is no protocol ACK on WiFi so it will need to be built into the USB protocol.
The kind of problem I see happening is issuing a Guide nudge over WiFi with a latency somewhere up to 1mS maybe enough to cause a problem.
For general command issuing that should not be a problem though.
