I can now bring a single charger that can charge my MacBook Pro and my iPhone. I just need a USB-C to USB-C cable and a USB-C to Lightning cable.
Charge my laptop or charge my iPhone or charge both (use the laptop as a passthrough).
It will reduce the amount of stuff I carry, I tend to carry just an iPhone charger while traveling in case I want to bring it with me where I don't bring my laptop, extra space in luggage and weight.
Increases utility over what? If the ports all match, you can choose to carry 1 or 2 cables depending on whether you want to make 1 or 2 connections. Since the ports don't match, you need a cable for each type of connection you might want to make.
Can you plug this particular cable into a wall adapter iOS charger? If not, then you still need two different cables depending on whether you want to charge from the wall or the mac.
