If you actually know what you're doing it's a solved issue in many situations. This type of image is a bit tricky because there are so many people in the image and they are further from the viewer than average. If you were to generate this at a larger scale, one section at a time, it probably wouldn't be an issue.

Also, something like this is super easy to fix with inpainting.

Odds are someone was just lazy and grabbed the first image that came out similar to what they were thinking of.
