I guess your premise is that someone did extensive research before building the meeting agenda, communication by mail and other means allowed everyone to do one's homework, and everyone actually did it, so the meeting is really just to seal the consensus.
I agree in this kind of situation, unexpected items are of limited scope, shouldn't affect the meeting agenda, and can be dealt at other time.
Now, this would be more the exception than the rule, at least in my experience. And if you can reach this point in your organization, I think you can get rid of the meeting altogether, and just validate the different points by mail or group chat.
