Opt-out and opt-in have definitely been talked about in other jurisdictions. In most cases, I would say that creators really don't favour opt-out. That's putting the onus on the creator when they haven't even been told that their work has been used. Now they're supposed to go through it and say, “Oh yes, my work has been used and now I'm going to put through some sort of request to take that out.”
There should have been permission asked going in. I think that's important for creators in the future: that they have agency over when their works are being used.
