While USB is now needlessly complicated and poorly labeled for consumer understanding, at least it succeeds in being backwards compatible so long as the physical connectors match (and all you need is a dumb adapter to convert any connector). If you have a 3.0 port on one device, a 2.0 port on the other device, and a 3.1 cable, you get 2.0 transfer speeds.
HDMI has the same kind of “issue”. Whatever the specs on each component, throughput and features drop to the lowest common denominator when in use.

USB ports are not labeled with numbers. You just made up numbers to name several different things.
This is why you think things are “poorly labled”. Your headcannon is broken, not the labeling.
