It's still incidental because there's zero impact on the shooter. None.

And in your example, I'm not calling that either for precisely that reason. If it dislodges the ball, I'll call the foul. If it doesn't impact the ball handler in any noticeable way, then I've got nothing. Just like the 100 lb pg running into the 250 lb center and falling off: I'm not calling the PC foul there, it's incidental contact because the innocent party wasn't disadvantaged (or displaced) in any way.

Your #2 point gets called a hand check due to the changes made, which do not apply to a single touch. If they wanted this to apply to a single touch, they would have said so, but this play in no way resembles a hand-check.
