I think the concern is that Apple will simply use this as an excuse to get away with including less in the box.
There are two ways of looking at this. One is that the savings from not having to include these peripherals would go towards offsetting the higher costs of designing and manufacturing these iPhones. The other camp would see it that Apple is simply charging the same (or even more) for less.
Personally, my charger is still sitting in my box, and I have been using usb hubs to charge all my accessories. Just got this baby a month back.
