> If they were doing this then there wouldn't be any ports described as "USB 3.1" (see point 4). The version of the standard is not just irrelevant but actively misleading to use in marketing material.
That gets to the edit I made at the end. The USB-IF Marketing group has never suggested marketing ports/cables as "USB 3.1". They've always preferred the "SuperSpeed {Bandwidth}" branding over "USB {SpecNumber}". There's a chart here: https://en.wikipedia.org/wiki/USB4#USB_3.x_.E2.80.93_4.x_dat...
(Admittedly, they are mixing messages by using "USB4 SuperSpeed {Bandwidth}" as marketing names for "SuperSpeed 20" and "SuperSpeed 40".)
But the fact that just about no one uses the USB-IF Marketing Names and instead reverts to easily confused "USB {SpecNumber}" branding is an interesting marketing failure by USB. (Not necessarily a technical failure of their specs.)
> On the port itself, sure, but if I'm buying a laptop online then it's pretty important what type of port it has, so saying "USB C T2" is a lot more useful than just "USB T2". How would I even know what silhuette the port has?
That's a slight goal post move from your previous comment about what to mark Ports/Cables. Sure, if you need to mark online materials you need to include port types. But it's still redundant on a physical port or cable to mark the port type when you are staring right at the port type.
