Eh it's not new, Apple is pretty much the reason tumblr got rid of nsfw content (I've heard it's sort of back now but idk I'm never going back to tumblr).
It's why even if an app in the app store is rated 17+ it still can't really have nudity in it.

NSFW content for tons of apps is buried in account settings that can't be changed from the iphone app but have to be changed from the browser. They've been doing this for a damn decade bro.
