This isn't about solving an existing problem. As you pointed out, pretty much everyone standardized around micro-usb almost a decade ago. That's mostly because Apple launched the iPhone with a proprietary but standard connector (the original iPod connector). So while all other phone makers had a special adapter and cable for every model, you could plug an iPhone on anything that worked with an iPod. Even the original firewire cable from 2003 would work with it.
What this is about is getting reelected and justifying to voters the usefulness of paying huge amounts of taxes to fund an EU-wide parliament. So they manufactured an (easy) problem to "fix". And it's going to be extremely popular since they'll be attacking and regulating "evil foreign tech giants".
