I'm not sure. As more devices and peripherals have gained USB-C, lots of horror stories of chargers frying devices and other catastrophic failures have shown up. This isn't my wheelhouse, but just from the reading I've done, it sounds like USB-C is a difficult-to-implement standard and that peripheral makers are more interested in getting something out the door quickly and cheaply. With the amount of power that USB-C can drive, this is risky.

If the end result is that you can't tell if plugging into your friend's charger is going to blow up your phone (or video game console), I think USB-C is going to fall apart.
