Prevents restores from consuming bandwidth, usability
The iOS 7 beta currently creates "ghost" apps on an iOS device when restoring from an iCloud backup, a report notes. When restoring from iCloud in iOS 6, a device will normally start re-downloading every app automatically once core data is back in place. iOS7, by contrast, will recreate folders but leave grayed-out icons in place of apps; only tapping on one will get an app to download.
Although it's unknown if the change will make it into iOS 7's final release, it appears to be a way of coping with a fundamental problem of restoring from iCloud. Simultaneously downloading every app a person owns can cripple bandwidth, and potentially render a device useless for hours. By forcing people to re-download apps only as needed, a device can become usable again in the shortest time possible.
