Exactly. I'm sure all these arguments were put forth back when batting helmets came out and the warning track was mandated. We take those safety measures as just part of the game because we grew up not knowing any different. It's just because this change is happening in the midst of our fandom that it's a big deal for some.
I like the change, but really, if you're going to do a rule change as a test, why not try it in the minors first and see how it goes so you can adjust any obvious flaws before you put it in the majors?
