Why would it need to? It only draws 1A @ 5V. That's well within what one would expect from a high-output USB2.0 or 3.0 port.

You're also not likely to be frequently removing and reattaching the power cable to the device, so who cares if there's only one way to plug it in?

Edit: Or are you talking about Displayport-over-USB-C vs. HDMI? If you are, I, too am disappointed that the CC doesn't output over DP or miniDP. Displayport->HDMI adapters are easy to come by (and one could be packed right in to the CC box), DP is technologically superior to HDMI, and its consortium is not run by a bunch of evil thugs. ;)
