And remember, there is some tiein between gnome3 and systemd. I don't know if systemd is mandatory (likely not), but gnome3 gdm is started differently, and has different configuration files.
Now there may be some need for CentOS 6.3 Some server software may not be easily installed on Fedora, which requires systemd... and required dbus, which may/can cause other problems. And then there is the problem of getting it scheduled by systemd properly. It uses a thundering herd schedule that by default starts everything all at once without sequencing. You have to give ALL the required prerequisites before it will work properly. And the usual sysVinit system doesn't work.
