All that will happen is that in a couple of years time, Apple/Samsung/Insert-your-chosen-vender-here will release a device that has both USB-C AND their new "son-of-lightning" connector marketed as way more whizzbang than USB-C and with a new charger bundled supporting said new whizzbang-son-of-lightning port
Nothing in the EU law says this can't happen - in fact I'd be surprised if Apple aren't already thinking along these lines...
Vendor marketing will simply be "use the crappy USB-C standard if you want, but ours is better because blah blah blah..."
And back to square one - same as PC vendors bolting RS232 ports into PC's for 20+ years after 99% of peripherals had moved on "just in case"
Biting the hand that feeds IT
