This is not correct: there is enough bandwidth for 4k@60hz, just not if you also want USB 3 speeds on the USB hub (which I have no need for: USB 2 is plenty fast enough). I am using a CalDigit USB-C hub with my 12" MacBook (which does not have Thunderbolt) with a special version of the firmware (you have to ask their customer support for a copy) that drops the USB ports down to USB 2 so I can connect to a 4k display at 60hz, and it works great.
