I think one thing that's important about this tech in the wider context of improving the entertainment value of baseball is that this gives the league a knob to tweak to balance pitching and hitting. Lots of words have been written already this season about the historically low batting average across baseball, fueled at least in part by balls with less bounce and thus more aggressive pitchers who aren't afraid of getting dinged. If MLB wanted to tweak a knob to get a bit more offense, they could shrink the strike zone a little - maybe take away half an inch at the top of the strike zone. With human umpires, there's no way that could be implemented consistently. But with this solution, it'd be consistent and could potentially even be done with no announcement and no rule change. If it's subtle, batters and pitchers might not even notice that they're being experimented on.
