I think the removal of the headphone jack is exactly for the benefit of future design, though. They're just trying to get it out the way now to soften the blow.
Although I will agree — I cannot see an appropriate aesthetic justification for its removal in the iPhone 7 — I have no doubt that future iterations simply cannot coexist with the headphone jack.
As I said, soften the blow now.
Removing it altogether before it's even necessary to do so is the exact opposite of softening the blow! What would not softening the blow look like?
Softening the blow would be shipping the iPhone 7 with lightning or Bluetooth earbuds but keeping the headphone jack to maintain compatibility with older accessories, then remove it next gen when people have gotten to try the new standard.
