“Everything must have USB-C” sounds great right now, but what about when it gets old and slow or something better comes a long that is worth the switch… we have to wait for the EU to tell everyone it’s ok and make a transition plan for the whole industry?

The entire point of the USB-C thing is so there is a standard charging port across all mobile devices. I doubt this is some sort of attempt at regulating the technology itself. If something faster comes along then it will organically become the new industry standard, just as every other USB charging port up to this point(e.g micro USB, mini USB). Apple is the outlier because they've kept their proprietary charging port for years, for the sole purpose of being able to set their own price for cables, dongles, etc... and preventing people from buying cheaper 3rd party options.
