I've said it on so many occasions, this just makes more sense than the system we have at the moment. There is still a 'hit' in there, but having players pre-bind makes it easier for players to find a bind on modern tight jerseys, and allows a second for the ref (and assistant on the short side) to check the players' binding's.
The 'hit' looks to have reduced in intensity somewhat, which imo is a good thing, because all the hit allows it a chance for the weaker scrummaging props an opportunity to get a jump against a stronger scrummaging opposition. This importance of timing it just right has a big part to play in the problems we have at scrum time, because a good deal of them are re-set of penalised due to early engagement. This could still be a problem, we'll have to wait and see.
I hope that the feeding is refereed. After all it's always been in the rule book, but has been ignored by most referees.
A step in the right direction. Time will tell if it will solve all the problems, but I think it's good to try this intermediate step instead of jumping straight to the removal of the 'hit', even if I think this is the eventual solution.
I don't think I've ever seen a prop bind onto a flankers shirt before! So I wouldn't call that a good example of what's happening in the professional world.
Correct binding is hugely important to scrummaging, and this law change makes it easier for players to get a proper bind, and for referee's to spot illegal binding = win, win.
