That's one interpretation. Cropping video content doesn't necessarily fall into that, yet I can see how some other designs would and why they would want developers to avoid that. Besides, there's also:

> Be mindful of aspect ratio differences when reusing existing artwork. iPhone X has a different aspect ratio than 4.7" iPhones. As a result, full-screen 4.7" iPhone artwork appears cropped or letterboxed when displayed full-screen on iPhone X. Likewise, full-screen iPhone X artwork appears cropped or pillarboxed when displayed full-screen on a 4.7" iPhone. Make sure that important visual content remains in view on both display sizes.

Emphasis mine.

EDIT: Also here [1]:

> Adhere to the safe area and layout margins defined by UIKit. These layout guides ensure appropriate insetting based on the device and context. The safe area also prevents content from underlapping the status bar, navigation bar, toolbar, and tab bar. Standard system-provided views automatically adopt a safe area layout guide.

The diagram shown suggests a "safe area" even inset a little from the notch.
