Yeah, but these rules don't need to be extended elsewhere. There are already tons of rules and gear that changes in popular sports based on the level of professional play... all the way down to swimming where professional meets have very different restrictions on suits, googles, caps than youth events. Also as the article states, for most younger players, these changes wouldn't be an issue as the goalie isn't quite big enough to cause the rules to be needed.
