What exactly does Apple documentation mean by "scene support"?

https://developer.apple.com/documentation/uikit/app_and_environment/managing_your_app_s_life_cycle

Scene support is an opt-in feature

Apps must explicitly opt in to scenes, which you do by updating your app’s configuration settings.

In iOS 12 and earlier, and in apps that don't support scenes, UIKit delivers all life-cycle events to the UIApplicationDelegate object.

However, apps by default, which aren't opted in, have a scene delegate and receive all life-cycle event reporting through the scene delegate (not the app delegate). This contradicts Apple's documentation, which wouldn't be the first time. Shouldn't the documentation instead state that multiple-scene support is an opt-in feature?

I think you're asking the documentation to be too pedantic.

If you create a delegate to handle scenes then you have "opted in" to scene support. The question of whether or not you can create multiple scenes is a related, but orthogonal question.

Even an iPhone that has a scene delegate can receive scene messages, but it cannot create multiple scenes.
