First off let's be fair here. Lennart has limited contact with Debian. The people switching Debian over to systemd are the package maintainers and Debian project leadership. That happened because Unity failed which had been the direction Debian was heading in. Blaming Lennart is quite unfair. Debian adopted systemd because lots of people in the Debian community thought systemd was better, mainly because upstream developers like systemd. Until you accept that you are going to continue with conspiracy theories.
As far as real world projects and systemd systemd is already being used in large PaaS deployment how much more real world can you get than that?
