I don't think it is my place to comment on that, because we are not a policy department. Our job it to basically collect data, and the thing that's on our minds is the quality of data. I think I can go as far as saying that the data are going to be of a lesser quality if it is voluntary survey-based.
How policies will deal with that, or whether it has any impact on policy development, is not an issue on which I am knowledgeable, given the nature of my work. You are probably better off asking policy departments for the answer to that question.
