It already worked before. The micro-usb charging was also an EU change because everyone was using their very special connector. (https://www.engadget.com/2009-06-29-nokia-apple-rim-and-othe...) Yet now we have USB-C.

(I don't know exactly "how" in this case)

Also it's extremely unlikely we'll need that for decades. USB-C as a connector supports absurd bandwidth and power. If you can pull 120W and drive 2x 4k displays from your phone... what would be the reason for the next upgrade? (and those are likely not the physical limits yet)
