iOS16: localIdentifier of PHAsset gets changed after saving to camera roll

Environment: iOS 16 beta 2, beta 3. iPhone 11 Pro, 12 mini

Steps to reproduce:

1. Subscribe to Photo Library changes via PHPhotoLibraryChangeObserver, put some logs to track inserted/deleted objects:

func photoLibraryDidChange(_ changeInstance: PHChange) {

	if let changeDetails = changes.changeDetails(for: allPhotosFetchResult) {

	    for insertion in changeDetails.insertedObjects {
	        print("🥶 INSERTED: ", insertion.localIdentifier)
	    }
	    
	    for deletion in changeDetails.removedObjects {
	        print("🥶 DELETED: ", deletion.localIdentifier)
	    }
	}
}

1. Save a photo to camera roll with PHAssetCreationRequest
2. Go to the Photo Library, delete the newly saved photo
3. Come back to the app and watch the logs:

🥶 INSERTED:  903933C3-7B83-4212-8DF1-37C2AD3A923D/L0/001
🥶 DELETED:  39F673E7-C5AC-422C-8BAA-1BF865120BBF/L0/001

Expected result: localIdentifier of the saved and deleted asset is the same string in both logs.

In fact: It's different.

So it appears that either the localIdentifier of an asset gets changed after successful saving, or it's a bug in the Photos framework in iOS 16. I've checked - in iOS 15 it works fine (IDs in logs match).
