New Rule 7-6-6 Throw-in Administration

[gamefaceref]

A mistake by the official giving the ball to the wrong team (error).....recognized before the 1st dead ball (correctable). Just because they are not adding it to the list does not mean we would not be correcting a mistake that was made on the floor. We can go back and forth on this but this is not what I am puzzled about.
Why can we put time back on in this case and not other the other errors? Or is that coming and this is a test scenario on how well we can manage the clocks to see if it can be expanded....
