I'm not sure pitch counts are much of a problem per se. Most managers will pull you before you can get a W if the situation/analytics calls for it. Ego makes pitchers want to go long, but at this point most of them know their W-L isn't what gets them awards (be that from the BBWAA or the arbitrators).
I think more than pitch counts it's high-stress pitches (both situationally and in terms of repertoire). I'm guessing Nola has been so durable because he just does not throw the kind of gas some of these other guys do, and his curve ball isn't as damaging as some of the other breaking pitches.
Certainly nothing is sacred in baseball despite the game preferring to act as though it is. (Best joke last weekend about the women's NCAA tournament games being played with different three-point lines at either end of the court is that baseball's like that every time).
Three-outcome baseball means higher pitch counts, which then also means more reason to pull guys before they face the order three times. And yeah, "chicks dig the long ball," as they said in that (dated) commercial, but nobody's really digging the strikeouts and walks, so that's why andy's idea makes sense as a way to actually make the game more "sexy" again.
