Personally, I'm excited for the change. Waiting any longer to adopt systemd could have had serious repercussions on the entire community (across distros). Big players are already using it; RHEL7 and CoreOS. It's time for a paradigm shift with our approach on managing infrastructure.
Both the sysvinit and systemd crowds have brought up great points - issues that needed to be addressed. The strong willed nature of the *nix communities is what makes them great. Strength in numbers. "Fighting" is a natural process; whether it's a team or a family.
Incredibly excited to see what kind of impact this has on computing as a whole. Time to learn something new.
