That was 2007 and when Iphone came the phone was unique and cool for the masses. It is 2015 and most users expect what I listed is working from start.
Again developers, like myself, are lazy and expect API is there already and want to use their time make apps not spend time hack low level coding that may break next release or not even allowed in store. For example if you are a employed developer that want to support SFOS you probadly don't have time playing with low level hacks.
