This is a new help page, and so it is just a first step in more transparency on this issue. That said, what you're referencing in the page applies extremely rarely, currently to less than 0.1% of news websites, and it is expected to stay that way. So, you are unlikely to regularly encounter this ranking signal. And even then it's impact is relatively small, only a few slots on average -- from the page, "impacted sites are not moved so far down in the results that they are effectively removed."
