Back when FIFA/IFAB changed the rule about passing back to the keeper sometime in the 90's, I was only following indoor soccer (Sockers!) and ignorant of the impact for years. When my boys got old enough to play on an organized outdoor team, their coach told me about it. I laughed. How are they going to call THAT? A little research will show that the transition was not smooth, with IFAB having to issue emergency amendments ("...obvious trickery...", lots of debate over the overlapping meanings of "deliberate" and "intentional", etc) when players started taking advantage of the loopholes in the change.
England just scored over Cameroun from an indirect kick as a result of that rule change.
