But why not just use USB4.2 2.0 rev2x2? Jest aside the USB-IF's stance (included towards the end) is consumer labels should be labeled on feature sets not standards revisions. E.g. the on the product it should say something like "USB 40 Gbps 60W" not "<cryptic standards name that supports 20 combinations here>". To that aim they are making a strong case for products adopting that style haha.

  I am enough of a power user to want to know what potential future use-cases some very expensive device will support. But I guess it's hopeless in a world where most laptop manufacturers can't even implement USB-PD to spec. I had a little bit of an hostile conversation with a 65W PD powerbank vendor over who violated the spec - the powerbank or my ThinkPad T495. Turns our the answer was simply "yes".

You mean USB 4 2.0 supports only 40gbps and you actually need USB 4 2.0 Gen2 for 120gbps. This is like the USB 3.1 Gen 1 vs 3.1 Gen 2 situation.

  More like we (as consumers and technologists) still haven't learned our lesson. A device supporting USB4 2.0 gen 2 doesn't mean that hard drive goes over 1 MB/s transfer rate. A display supporting HDMI 2.1 doesn't mean it will output anything better than 1080i. Specs are meant to describe interoperability. Conformance provides assurance that they're _is_ interoperability. Certifications (like Thunderbolt 4) provide assurance that they actually support certain features, and that they are supported in a way that matters. But specs like USB 3.2 are completely forward compatible. That means they describe how a say a conformant USB 3.0 device _is_ a USB 3.2 device. What they add is a way that devices and cables that want to support 20 Gbps can do so in an interoperable manner. They don't mandate 20 Gbps support if you say you are a 3.2 compliant device. When device makers and cable makers label them with spec internal names and subsections rather than the official marketing terms and logos (like USB 20 Gbps) it is an indicator that they haven't actually proved that they are conformant with the spec, or that they properly interoperate with others who are. The market can solve this by preferring parts that aren't sold in consumer hostile ways. Problem is, those parts MAY work and usually ARE cheaper ;-)

The IEEE 802 family naming seems straightforward by comparison. I'd love something like USC C 3.1.zxcvbn where it goes {form factor} {major}.{minor}.{capabilities}.

You see when industries get so big, people make committees to oversee how things are done. These committees tend to have (or at least give off the feeling of) a lot of power with little actual work being required. I’m sure most here can think of colleagues from the past that would be the kind to fill this role, and that’s your answer.
