It may be a big opportunity for Apple. After all most of their income comes from device sales, not from app store. Offering tools for parents which make them feel good, might cause them to spend the extra $100-200 per kid and get them iPhone instead of cheaper Android device.
Of course others could follow with similar features and this would remove the possible advantage Apple had, leaving them with no advantage and reduced app store revenue. Or if others don't follow, this might drive developers to other platforms.
