tbh I don't think FIFA is all that worried about the 3 or 4 countries where soccer isn't big. Nepal, Australia, NZ aren't going to send them broke.Purists wont like it but Soccer will struggle to break into markets they don't already dominate without that rule evolving. Soccer compared to other national sports is pretty boring.
When cricket and baseball are more exciting to watch then the sport has issues. I'd rather watch an IPL game than a non-world cup soccer game and I find cricket boring.
