You do know how standards work right? They get revised with time. Did you forget we had headphones jacks at least that long, USB A. Lightning has gone unchanged how many years?
If phone makers feel a need to change charging port now, it’ll likely be to go all-wireless. If wireless charging ends up nearly as fast/efficient as USB what’s the point of USB? (for devices that don’t need super fast data transfer)
EU doesn’t prevent going all wireless I believe. Apple Watch is not getting banned.
