That’s not the case here. Think of this as each app having a folder in your iCloud disk without being able to see other apps from different developers. As long as you don’t delete the app, the folder comes with you as you move from device to device so the apps installation is not required each time.
Sounds great while iCloud is up/you use iOS...prepare for the shitestorm when its not or the user decides to leave Apple... 'Easy' and 'Convenient' won't be the terms anyone is using.
