A long requested ability on an iPhone might finally be fulfilled. According to AppAdvice you will be able to delete Apple stock apps. Usually having to hide them on another screen or within a folder, etc. it looks like iOS 10 includes code for removing the apps altogether.
In the iTunes metadata there are two new keys labeled isFirstParty and isFirstPartyHideableApp. These boolean-valued keys appear to give the ability to hide particular apps.
We will have to see if this becomes a reality by the usual June developer release of the next iOS.
