So if the count is 3-2, there is a shift infraction at the point of release, and the batter pops the ball up to the catcher for an out. It's a walk, instead? Could be the difference between post season or not, etc. Ya, I realize the likelihood is very very low.
No different than an offside disallowing a goal, or shot clock violation. Just seems like potentially extreme consequences for minor things - like being 0.5 sec over on the pitch.
