If you are saying that this is a piece of Law that is (or should be) widely ignored , then I am in agreement.
But why? The is quite clear, no-one is permitted to handle the ball in a ruck. It doesn't say except the Srum half, so why do we allow it? It's common sense. Otherwise we'd be blowing for scrums all over the place. As a Prop, I don't want that lol.
Similarly in this instance we'd in theory be enforcing/allowing something that's not specified in the Law. The Kicker means the same kicker to you, it means whoever is going to take the kick to a few of us. To us, the fact that it doesn't say the same kicker implies that a different kicker may take the kick. For you (@cr), you believe the fact it doesn't say a different kicker can take the kick implies that it must be the original kicker.
These are 2 interpretations of this Law. What if WR come back and just say, it's up to the individual ref? Granted that's not going to help and I'm hopeful that a more helpful reply of either "it's the same kicker" or "a different player can take the kick" will be forthcoming.
