As a guy who wears stripes on Fridays, I can tell you that we do not make the rules - coaches do. If coaches want the rules changed, they need to contact their rule-making committees.
As far as this foul is concerned, it seems pretty simple. Yes, it can be a judgment call. Typically, I follow "Stripes" approach -most of the fouls are covered by another rule. For example, the cheap shot 20-30 yards behind a play is, quite simply just that - a cheap shot. That's covered under UNR or other rules. Most coaches don't want a player injured, whether it's on their team or the other and don't coach that way.
Finally, I'll just say this: if a coach supports the blatant attempt to injure an opposing player (which that "earhole" shot is), then that coach needs to question whether or not he's in the right profession. Sportsmanship is a fading virtue.
