USB-C fulfils that already.

It doesn't work out economically because big networks of usb devices (ie. Hubs) all need the power components if one is to maintain the generalisability of being able to plug anything into the grid anywhere.

USB has significant length limitations and the cabling is generally not plenum rated. It's also silly to have a cable with wires that will never be used beyond negotiating for power.

USB-C is for short distances (<4m) and is more expensive than CAT6 cable.
