The USB versioning makes perfect sense when you think it as the version of the standard, literally the document itself, which encompasses all the modes. And it does make sense to have single standard instead of having the information scattered across dozen historical standards that have been partially superceded. I would point out that this is not a new thing. The situation was exactly the same with USB 2.0, technically it was perfectly correct to call compliant full speed device "USB 2.0", because 2.0 did indeed include full speed mode (as does presumably all the USB 3.x standards)
