I can understand that Al, sheet code variations do open an unnecessary door for many collectors. Especially since they exist in more sets than most of us realize. If you pursue them in one set you're almost obligating yourself to look for them in the rest. That would be a arduous task if you ask me. You've got to draw the line somewhere, right? I do think, however, they should be added to the master list considering they are actual variations and not just printing anomalies.
