I don't understand the 'never gotten usb-C' part. Modern phones have more than enough space for two connectors. So usb-C next to a micro-B charging port is no problem.
After a while, almost all phone also have usb-C, most people like usb-C, so the industry can petition to replace micro-B with usb-C.
Are there any examples where the EU mandates legacy stuff that is no longer useful, but still has to be kept anyway?
