It's been tested, in fact, from the testing that's been done, even a non compliant charger shouldn't damage the Switch. And no one's complained of being bricked by 3rd party chargers. These 3rd party docks are doing something to brick Switches that the chargers aren't. Maybe it's the combination of bad dock and bad charger that's doing it, who knows. All we know is that these unofficial docks are doing something special that's bricking Switches. Chargers alone don't seem to do it.
