There's definitely good candidate sites that aren't on this list and we'll be moving into the next phase of this project after we look at the data from these twelvethirteen sites, so stay tuned. If your site thinks this might help because, have a discussion on your meta - this isn't a one-time event. Once we figure out the impact of this change on sites, we'll be better able to decide when we think we can just change the setting without needing to watch things as closely.
