Nah, it's just yet another instance of the Demo-Only Feature.
These are now more important to the creating-companies than the actual user interface/UX.
The DOF is something which is:
* ONLY useful for the duration of a presentation of its newness to non-technical people (eg salesmen, journos)
* typically a negative for prolonged use/users.
Example: the macosx Dock.
Example: the win10 Dynamic Game Panel! on the startmenu.
Example: transparency on the desktop.
Example: the "flattened" affordance-deleted Modern Interface! meme of maciwindroidux.
