I agree that something must be done, but the hydration break is the wrong solution for two reasons.
First, plenty of countries have been regularly playing under these conditions and will keep doing so after the World Cup. Too hot to play in the afternoon? Play at night.
Second, and more important, it changes the game in a major way because playing for 90 minutes with a single break is not the same as playing with three. I imagine data will say whether this has an effect or not, but I cannot imagine that an endurance player would feel the same if they have to always stop halfway.
