In that case either the charger or the Switch was faulty, no matter the protocol in use, the devices should negotiate which charging profile to use. You can't blame a non-spec implementation on the protocol, that's on the manufacturer.

From what I've been able to see, that specific issue stems from a combination of cheap chargers/docking stations and Nintendo changing the USB-C port tolerances to allow smooth sliding in and out of the dock. Again, don't blame the standard if the manufacturer decided to implement their own crappy version of it.
