There is really nothing more to say to this news report.
To give some context, Germany is currently in coalition talks for the forming of a new government and the Social Democrats(SPD) are screwed. They promised no more coalition government before the election but stepped back on that. The party voted by a hair to take up negotiations for a new coalition, during which the prime candidate(Schulz) was completely abandoned after trying to give him the post of former SPD foreign minister Gabriel. Now they face a party vote on getting involved in a new government and they fall in polls almost every week[1].
I'd be extremely surprised if this becomes a real project.
