Well now that the Bryson's and Reed's are out on the LIV tour, that'd be like 80% of the "that blade of grass is slightly brown so it's a divot I get to lift, clean and place it."
One odd thing is that for USGA events if they do lift clean and place, the distance you can move the ball is "less than a scorecard" since everyone has identical USGA-issued official scorecards. The PGA gives you an entire club length so you often see big improvements, especially around the green, for lift/clean/place. Just make the wording that the ball is noticeably below the normal surface of your own fairway. Have one player in your group verify. Lift, do not clean, place the ball within 6" of the divot no closer.
I get the "it'd be too subjective" argument to some extent, but the rules of golf are absolutely packed to the gills with judgments left mostly to the player and their sense of fairness/honor. The other issue is that sure, on PGA Tour courses you don't usually see that many divot lies in critical moments. Yeah well they have a billion people manicuring the course morning and night to ensure every divot is filled, weekends have small fields, etc. Those rules filter down to all other levels of play, and I've played in events where players were intentionally missing fairways because landing areas had so many deep, completely unfilled divots that were basically one-shot penalties if you found one.
How do you change the "stones in bunkers" rule but not divots...
