Similarly, I’m glad Tesla convinced all the other American manufacturers to go with NACS for the American market because the CCS plugs are monstrosities.
USB-C suffers from unclear naming problems sure, but in my experience most of the problems are actually caused by shady marketing pages. If they just clearly marked cables and ports with their capabilities, using the same physical connector would only be a benefit.
So no one is going to pick a theoretical "USB-D" that requires every cable to be able to carry 40 gb/s to be a standard. I don't need a 40 gb/s cable to charge a battery pack.
All the weird data transport, seems like a big pile of maybe it will work, maybe it won't. I think most cables will do usb 2.0 data and probably usb 3.0 data, which covers a lot. I've managed not to need any of the other things, so avoidance seems to be pretty good. The one exception being the nintendo switch that does hdmi over usb-c, but sticking with their dock works enough for me.
