True, but you can't legislate good command into the game. The zone has "expanded" to allow for more strike calls (truly its not expanded; better umpiring, aided by pitch tracking, has caused the called zone to more closely match the rulebook zone). And ironically, Manfred talks about doing the exact opposite - chopping off the bottom third of the zone, in order to necessitate more "action," ie. pace of play. Seems pretty clear this would actually lengthen games further by leading to fewer strike calls, more walks, etc. the exact opposite of the type of game you are describing.
