The point is that this proposed rule change is being vaunted as a positive thing for all non-Tier 1 countries, however it will be extremely disproportionately advantageous for the Pacific Island nations, as they will a far greater 'pool' of players to choose from than all the other non-Tier 1 countries, and your whole point about cultural ties being very important for Polynesians further illustrates that they want this rule primarily for their own benefit (I'm speaking about the concerned unions), not for the benefit of the game as a whole.
I want other countries to improve, by all means, however as soon as we start implementing regulations that favour one set of countries over another, then we start going down a very, very murky rode, that is best left untrodden.
