@kinggo, you are right, multiple protocols over the same physical interface are a problem but not the problem. My main objection to USB-C is the lack of compatibility. I have absolutely zero USB-C devices so obviously the first one with a USB-C only connection would be a major compatibility problem, forcing me to spend more money. And to what end? It does not give me any advantage that I can think of. No functionality I was desperately waiting for and could hardly live without. For all intents and purposes, it is "progress" for its own sake.

USB-C may be the future but t is not the present just yet. Once USB-C becomes the mainstream and there is no way to obtain "old" USB devices, then I will succumb too.
