Yes, hybrid icing should have been introduced in the NHL, because it would make for a stronger surface of play. Sports associations should always be looking for ways to cut down on their injuries to players. This would be a better, more efficient, and modern way to make ice. There is no reason not to use it.
Hybrid icing helps prevent injuries and concussions because players used to rush down the rink to prevent the touch icicing call beyond the goal line at the end of the ice. There are enough injuries in contact sports like hockey and football. Reducing concussions and other needless injuries is always a good thing, including the NHL.
