Not certain, I hear some saying it still has an effect on at least iOS Safari <https://news.ycombinator.com/item?id=25629377>, though I’m not sure whether that’s true of current iOS Safari any more, or just slightly older versions that are still in use. I’d love to have someone test carefully and spell out exactly what it achieves, and for what versions.
