Actually, I think that you are missing the point.
The principle at work in your example of ignoring a throw-in plane violation with only 5 seconds left is that a team should not be rewarded for doing something illegal. That would be the case if the official stopped the clock to call the violation.
Now please tell what benefit does the violating team get in any play proposed in this thread. I see no reward for the illegal action. Thus it should be penalized.
Even in your first example with a defender violating the FT lane space and then pushing or pulling the shooter over the line prior to the attempt contacting the ring, how in the heck would he know whether the try is going to be successful at that point?
