If the industry comes out with a new, better connector, they can use it, as long as they also provide USB-C ports. If enough of them collectively decide the new one is superior, then they can start using that port in favor of USB-C altogether.

The EU says nothing about USB-C being the bestest and greatest, they only say that companies have to come to a consensus and have to have 1 port that is shared between all devices for the sake of consumers.

I personally much prefer USB-C over the horrid clusterfuck of proprietary cables that weren't compatible with one another, that's for sure.
