The main reason for that is that the number of coaches familiar with other stats isn’t very high. As more and more stats become more readily available, that’s changing. Not because those aren’t good indicators of performance, but because using other stats in conjunction with them only make the final “product” more valid as a way to make managerial decisions.
I like some of the discretionary stats that don't fault players for having good at bats (where they don't necessarily get a hit).
I’m not sure I understand what a “discretionary” stat is. As far as I know, the only “mandatory” stats are WPct, BA, SlgP, FPct, ERA, and OBP. 
Its no accident that those are the only percentage stats that MaxPreps incudes in the player stats. The problem with other metrics is that since they aren’t in the rule book, they can mean something different from venue to venue and person to person.
But seriously, no stat really “faults” a player. All they do is show what a player’s performance was using the criteria used to run numbers through the algorithm. Its people who determine what is good or bad or success or failure, and most people have different values for everything.
