David's answer is an excellent one. I think there's been a bit of a theme about the need for some amount of flexibility here. We've had it on a number of the kinds of issues where, once you start coming up with real-world examples or potential real-world examples, it starts getting more and more difficult to come down with a specific response.
Flexibility sometimes can be a bit of a feature, not necessarily a bug. There is value in that flexibility. What then becomes essential, though, if we recognize that there is going to be that flexibility, is how you ensure that you have appropriate oversight and review as part of that process, and transparency more broadly, so that at least we understand how some of these things are being interpreted, and can better understand whether or not it's consistent with what many people would think is reasonable.
