My point was that PoE, especially with the recent revision, allows for very useful levels of power to be drawn, so if you're going to have an 'embedded' system with an Ethernet port, I would think it'd be useful to use it.
Why plug in two cables (USB-C (power) and Ethernet (comms)) when you can just plug in one?
It doesn't draw anywhere near that. 15W max (for accessories), and 7W in heavy use (without anything other than the board itself).
