If the pitchers are getting too good, just make it harder to pitch. Don't make it easier to hit better pitches.
Golf is also an arms race too. Look at the lengths of golf courses over the last 50 years. It's comical. It used to be 6000 yards was a championship course... now it's over 8000.
They used to put bunkers in front of greens to make them more challenging, but the equipment evolve to maximize height, and stop the ball on a dime. It's completely convoluted, because we just keep letting technology overcome every obstacle, but players don't like the obstacles, but you're not supposed to like the obstacles. So we let the tech overcome those obstacles, and then we build new, more difficult obstacles, and it's a never ending process of legalizing more tech, and then building more obstacles. And it continues until the game is unrecognizable from what it was a half century earlier.
There are discussions about lowering the seams (harder to generate spin and makes the same spin rates less aerodynamically effective) as well as lowering the mound.
