Cool, thanks for the info, makes sense. I also prefer to do non-aggressive loading as a dev, but for some of my apps I got lots of feedback from users that loading images that way "felt slow and laggy" since they are used to aggressive loading in other apps...

Exactly. To be aggressive in loading is kind of risky since doing it poorly can lead to a non-responsive behavior in the app. App developers can always choose to be more aggressive if the default behavior is not aggressive enough, but if the framework chooses to be overly aggressive, it prohibits some apps from adopting the framework.
