At some point, maybe, in the near or distant future, Apple could throw you a bone and let you free up some space on your iPhone.
According to CEO Tim Cook, Apple will eventually figure out a way to let your remove those pre-installed apps you never use. Like Apple's stocks app, or the default weather app, or the Apple Watch app.
Cook said this in an interview with Buzzfeed, claiming Apple "wants you to be happy" and it's not trying to "suck up your real estate.
“This is a more complex issue than it first appears,” said Cook. “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 [for you to remove them]. … It’s not that we want to suck up your real estate; we’re not motivated to do that. We want you to be happy. So I recognize that some people want to do this, and it’s something we’re looking at.”
Basically, Apple doesn't want you to get rid of all of its base level apps – but it knows you want to. In the end, Apple might just compromise. No, you can't delete the notes app – but we'll let you trash that crappy weather app.
Is the end of that ubiquitous junk folder night? Probably not, but Apple might let you free up a little space. And every bit helps.
