Apple has added two new keys labeled “isFirstParty” and “isFirstPartyHideableApp” in iTunes metadata. These two new values started showing up a few weeks ago on every app in the App Store. The iTunes metadata is where all the information about an app is stored. It shows things like the date it was released, the App Store category it’s in, its size, etc. The new keys suggest the ability to remove apps such as Stocks, Compass, and Voice Messages is coming very soon.
