Expose Output > Post Processing > Dither in image output settings.

The dithering settings adds some slight noise to the image to break banding. However this isn't always desired (for example flat, silhouette, overall stylized renders), and the setting is somewhat obscure, which leads to many people not knowing it exists.

I am not suggesting for dithering to be disabled by default but rather just have it in a place where more people can see that it exists, like in the file output settings when saving images. Other non destructive steps are also exposed here like the color management.
