Some leagues are replacing with Fighting majors. The origins of PIMs was to reward toughness, but now that the internet stats are more complete, especially with Hits, some leagues are changing. BUT it must be noted Hits are not an objective stat, and there are rink-to-rink variables in how they are defined. For this reason, my preference is to replace PIMs with Fighting Major penalties. It's fun to have a tough guy on your team, and fighting is a part of the game. And, as you note, hooking and tripping penalties are never good and should not be rewarded.
