No, we're not forking systemd, we're talking about configuration. 

This is like saying that booting your Linux desktop at a different
runlevel is forking Linux.

We're saying that graphical init scripts need to somehow tell the system
they're a graphical init script. There are only a small number of these
out there and adding some identification to them whilst an annoyance,
isn't a big issue.

Integrating new technology like systemd into older systems is hard. You
sometimes need to add new information to allow the system to work
properly. This is once such case.
