According to Tim Cook, Apple is "looking at" letting consumers get rid of pre-installed iPhone apps that are rarely used. These are the ones you mostly always hide away in a folder when you set up your new iPhone: Compass, Stocks, Podcasts, Tips, etc.
“This is a more complex issue than it first appears,” he said. “There are some apps that are linked to something else on the iPhone. If they were to be removed they might cause issues elsewhere on the phone. There are other apps that aren’t like that. So over time, I think with the ones that aren’t like that, we’ll figure out a way
In iOS 8, Apple added Health, Podcasts, and Tips as default apps. With iOS 9, Apple added Find My iPhone, Find My Friends, and News as the latest apps that can't be uninstalled.
Clearly Apple is trying to make distinction between apps like Mail, Safari, Camera and the App Store — and ones like Compass, Stocks and Tips, which don't play a vital role in iOS as a whole and don't impact other apps.
Currently it's not clear when, or even if, this might happen, but the sole fact that Apple is considering it, can surely make Apple fans happy.
