I think you are right.
I will also say, though, that on the calls Harp goes ballistic over, he's almost always right, meaning there is plenty of room for improvement on the part of the umpires. They should go back to those big chest shields so they can line up without regard to the catcher. That might be a start.
They need to put a chip in the ball and when it crosses the strike zone, a beep goes off in the umpires ear and he signals strike. It will be a seamless experience for the fans. I'm sure the techies will come on here and question the technology but I have faith that the geeks will figure it out.
The purists will say it will give an advantage to the hitter or pitcher and I think that's a valid discussion to have.
