I urge you to look at IP (v6) stacks that are small enough to be feasible on small microcontrollers, or even better, their spec, e.g. 6LoWPAN, and all the trade-offs and shortcuts they have to make. Then, re-evaluate if the increased complexity and energy consumption is worth it, e.g. just for a mouse or keyboard. Then go ahead and specify how you want this spec to have comparable compatibility modes to USB-C, e.g. if you are going to run displays and external hard drives, as well as HIDs and power... Considering the alternatives, USB-C is not too shabby for the intended uses.

I didn't have mice or keyboards in mind, but yeah, a full stack would be surely overkill for their minuscule uCs; this would call for more intelligent devices, peers rather than slaves, which for smaller ones would be a problem now. I'm far from an expert and you're 100% right on the involved complexity, still I dream of a standard for devices and systems where just adding a software layer can extend a board to board communication to a geographic level, and Ethernet seems very close to that.
