The MacBook 12" was introduced in April 2015, nearly three years ago, with just one USB-C port and a stereo jack. Nonetheless, USB-C devices have been introduced in a glacial pace (I bought a 12" at the end of 2015 and there was still almost no useful USB-C accessory available). We'll eventually get there and I agree that things will be messy for a while, with USB2-only USB-C charging cables, MacBook Pros that support Thunderbolt over USB-C, MacBooks that don't support Thunderbolt over USB-C, etc. (I do like the plug though, it's reversible and compact.)
