While I too am disappointed when any game elements and animations are wholly removed from a game, many of the things you're listing and mentioning here add to the emotion of the game. And I think that's what SCEA tried to avoid removing and instead tried to cut pieces they felt didn't impact things one way or another as far as emotion goes.
Obviously, it's a debatable topic of what should/shouldn't be removed if they absolutely have to remove something, but I perhaps naively believe this is where the line is drawn for the most part, barring actual MLB rule changes to speed up the game. It's when they start cutting out the things in your list is when they not only affect the flow of baseball, but also the emotion and tension of the game. And I can't picture them doing that.
But I agree with the sentiment that it should be implemented as an option rather than changing the Broadcast gameplay. Maybe have a Fast Play, Broadcast Fast, Medium, Real, etc. or other solutions that have been mentioned. Here's hoping baseball-simulation fans of all the various paces can one day co-exist.
