One would hope, but these aren't shady Chinese knockoffs having these problems, these are Nintendo and Apple products. Part of the problem, though, is that the worst-case scenario is so much worse than before. If your regular USB accessory is shoddy, it just... doesn't work. But since USB-C has the capability to transfer tons of power, having something go wrong can have much bigger consequences. Also, as mentioned in another comment, you can't have things like a hardware fail-safe to prevent a certain amount of charge from going through a port, because they're intentionally left under the control of software, because sometimes maybe you'd want that much power going through there.
Nope. Not officially, one reason why I am against iPhone dropping lighting for USB-C. That was few years ago when no one see or believe this mess is coming.
