No, world first needs devices with drivers, where you could use such open systems (which already exist actually).

Someone made a nice sequence:

Maemo: DEB, GTK
Meego: RPM, Qt
Tizen: DEB, EFL
....
What's next to be expected? Something like XXX: RPM, Clutter may be?

Someone either likes hopping around for the joy of the change for the sake of change, or someone just doesn't think too much, or doesn't care about any previous effort.
