Lite av en känsla som beskrivs i denna post får man helt klart: http://bgr.com/2015/10/21/iphone-6s-3d-touch-...
"If it wanted to, Apple could have introduced many additional 3D Touch gestures during the iPhone 6s event that may have completely changed the iOS 9 experience for iPhone 6s users. But the company is interested in offering the same set of core features to all iOS users, regardless of whether they’re on the iPhone 4s or iPhone 6s."
"Yes, there are differences between devices, as certain iOS features require specialized hardware. But, essentially, apps behave similarly on any iOS 9 device, no matter how the user chooses to control them. By not using 3D Touch for anything else other than shortcuts, Apple is preventing fragmentation and making the job of developers easier."
