I assumed Elias was trying to get more outs to help not abuse the bullpen as much. Lets say the new dimensions allow the starters to average .5 more outs per start. That's 40 less outs we need from the bullpen, which helps us not play AAA roulette with whoever has options to fill out the extra innings.
Maybe the possible extra rest for the bullpen will add another win or two for the year. Although, it doesn't seem to help the A's very much.
