I was going to add a little point there, but my hand up to my colleagues didn't really work.
Maybe I'll give you, MP Au, a bit of colour from our perspective.
The intent is to continue to try to go voluntarily in this space, especially after the 2014 Spencer decision we talked about. I can speak for us in saying that the stickiness, so to speak, to use Norm's example of those who need a piece of paper, has largely been in the telecom sphere. What this does for us is give us a backstop so that if we can't get it voluntarily, we have the authority. It's hard to say the number because it would depend on whether that stickiness persists or whether, because it's legislated, we get less of that. It is the response that would dictate that.
