This is not true. Apple's own apps, like the Weather widget, will display location permission "nag" screens occasionally just like third-party apps do.

Apple Maps doesn't use your location in the background. It only uses your location while the app is open, or while you're actively navigating using it.

Apple Photos is your photos. It'd be weird to warn the user that it "has access" to itself.
