Then installing/deploying these apps on a read-only partition doesn't make much sense in the first place.
otherwise why allocate disk space to be read only and have apps on it people might not want? (as far as user experience is concerned)
i meant they can maintain an app store experience without the bottlneck of downloading expected apps on day 1. instead of downloading and using data an wasting time, it would enable the app. so its the same "opt-in" experience as downloading but with benefits
