Are you talking about the thing where sending 9 volts on a data pin fries the switch? I don't blame the spec or Nintendo for that one.
That cable is more of a complexity problem, but it wasn't because it misrepresented capabilities or anything. They put in a chip which didn't reset the connection when you unplugged one end. I don't know if that's really a spec problem, though.
The Nintendo Switch can get fried in dock mode (and Nintendo usually has pretty top notch QA/abuse testing outside of joysticks)
Here's a report of an A to C cable on fire from Anker (another pretty well regarded manufacturer) https://www.reddit.com/r/Android/comments/7j3k38/anker_usbc_...
