The other recent rule changes were done primarily as a way to offset coaching and strategy trends that had negatively impacted the game (i.e. limiting the shift, limiting the amount of pitcher substitutions, and trying to ensure speed, baserunning, and stealing remained relevant). These changes were very successful because they were helped to return the game to its roots. The one exception to that is the Ghost Runner in extra innings, but that was probably worthwhile in order to end the occasional marathon games that would occur.
This proposed change is just idiotic in so many ways. Think of the impact it could have in player statistics, which is one of the great advantages that baseball has over other sports. I wonder how many extra HR's or RBI's Aaron Judge would get in a season if he was given an extra plate appearance every game.
