I wouldn't put my money on itemview-ng. It's a great research project but not much more. Not to mention that it will take years until it become part of QT.
I would suggest to all angry people download Harmattan UI Framework, review code, suggest new apis and ideas and help us make it a mainstream framework (for instance many comments from zchydum are already in master). There is a lot of things to do for everyone.
However I agree it's fun to blame developers which secure their jobs for fragmenting frameworks. Haha. There are only 2 guys in libdui who still work since the beginning of project.
