Correct, thanks for reading the actual regulation

It does specify USB-C as the common charger port for now, of course (with support for future charging protocols over USB-C). And it does allow for technological evolution

(And of course the margin of improvements in wired charging diminishes over time - I think such regulation would have been more problematic before USB-C came along)
