I think it probably has. The clock has certainly made the game more enjoyable for the fans. But, I don't think that's the key point. The teams and analytics staff have studied what leads to winning teams and successful pitchers. I don't think winning teams abuse their pitchers. They know that high-spin rate and high FB velocity yield results and they know the mechanics and conditioning that produce them. This is like asking whether the fans find NFL football which has reduced the valuation of running backs and barely mobile QBs, while increasing their valuation of linemen and highly mobile QBs more enjoyable. Fans want their teams to win. That is what sparks fan interest. I do find mobile QBs to be more exciting. I also enjoy watching the DL, especially the edge rushers. NFL teams have determined where to spend the $ to maximize the chance of winning.
Btw, given the long 162-game season, as a fan I'm more interested in reaching the playoffs and getting back to the WS than I am in a single game, like Lorenzen's no-no. His Phillies games prior to that were very good, that game would have also been very good if he were relieved after 7 IP. We would have been spared the subsequent poor outings and the Phillies would be closer to the team goal. Certainly, the fans who saw the no-no will never forget it. But, just one game in a very long season and the playoffs are far more exciting than the regular season.
