Bro, kids aren't going to be less enthused about playing hockey because their goalie's pads are slightly different than what they see on TV.
Hockey is already expensive - for goalies especially. More rule changes = more $$$ spent, and not always for great reasons.
Where I’m from in northern Ontario, a hockey centric place in the world, more kids played in recreational leagues than at the local barn rinks. Sure, playing shinny is really fun, but at the end of the day, kids want to play hockey as seen on TV. Whenever I went to the barn rink with my goalie equipment, people loved it because it was one of the few times they actually could shoot on a goalie. Playing posts or with a fake goalie is just as challenging (given I wasn’t very good) but it’s not the same as the real thing.
