It would be worth fixing with a fully open design.
In other words, you accept that it *IS* better, but you are prepared to put up with the currently worse open designs, because they are open. Much as the users of desktop Linux are using an inferior OS on the basis that openness trumps usability for them.
Or it could be fixed with color coding the shell around the connectors.
It would help, but it's still inferior to a design that doesn't need looking at.
At the same time, I don't see a bunch or people ripping their hair out because their house key needs a particular orientation.
Because the keyed side and the smooth side is so very clear, with or without looking. And they use their house key often enough that the up/down orientation of the key is remembered. This doesn't tend to happen with USB plugs of all types. People need to look at both plug and socket to match them up each time.
