You make a good point about how the forward pass will continue to be refereed in practice, Ian_Cook. Wayne Barnes would agree with you about outlier ideas!
For example,those who don't like the fact that a knock-on into in-goal is a scrum 5m with the defending team put in, who then argue that the referee should play advantage as a subterfuge then call it over to award the defending team a 22DO instead. This is the type of advice that young/new referees could frankly, do without
As for Barnes, well his blind spot when it comes to his understanding (or rather lack thereof) of what constitutes a forward pass is out there for all to see.
