New proposed offside rules

So there's a new rule being proposed and studied called Wenger law. It's an offside definition in while the whole of the attacker must be past the second last defender to be considered offside rather than any part (save the hand)

So thoughts on this proposed rule? Do you feel this would make it easier to call offside or add a challenge?

I'm curious how it would work. Do we go for the feet as a reference point or we have to see a gap? It can get tough when the players are bunched together.

I should stress I'm not opposed or think it's a dumb idea. I'm just curious about it.
