The features are definitely
part of KitKat, and the KitKat update for the AT&T One definitely includes the feature (see the
AT&T Consumer Blog post). The other versions of the One do as well; I received the update for mine (T-Mo) today. It'll take an update from third-party app developers to
enable them, though.
Edit: to clarify, it's certainly still up to the OEMs to modify or exclude features as they see fit... what I was getting at with "barring any changes that specifically remove the feature of course."
