It is a strange, smart, somewhat pompous regiment to embrace in habit. The pin effect has, in truth, evolved (changed) over the 6+ years I have been here. Changes that have developed into the exotic, at times. Heck, I have even saved 2 or 3 replay foul-ups as reminders that "no flag" is the best choice 95% to 100% of the time. To hit a few flag-sticks and produce an OB/ lost ball result are excellent eye-openers.
