[CentOS] Design changes are done in Fedora

Just to note: Fedora has been upstream for RHEL for many years.  New
features are tested in Fedora for a long time before they hit RHEL.  For
example, systemd was first introduced in Fedora 15 (we are currently at
21).  Ample time has been given to discuss, critique, provide feedback and
to help shape what ends up in RHEL.  If you are running RHEL/CentOS,
consider running an instance of Fedora in a VM or testing environment so
you get years of warning about new features before they hit RHEL.  If you
are concerned about what happens to RHEL, get involved:
