From what I'm reading, most of the violations Nathan is complaining about are on the part of Nintendo's dock, not the Switch itself. Moreover, these violations are all relatively minor (especially compared to Nyko's 9V CC howler!) and are unlikely to cause any serious issues under normal use.
The point was not whether the implementation in the Switch was perfect, it was about frying the console. Minor spec violations won’t do that, but a wildly out-of-spec charger might.
