No, the support for USB 3 really relates to the root hub (e.g. the xhci driver) and some other minor hub changes for USB 3. Support for new USB classes, like the ones linked to, is generally separate. Someone who wanted to could probably start on that driver entirely independent of my work, at least if I'm reading the basics of it correctly.
