If you have a simple command that give you a list of new
symbols then this is easy to script as Michal also
shows with the below example.

listnewconfig is for everyone that like to see a list of new
config options - without touching the current configuration.

By limiting listnewconfig to do only one thing you actually
create further uses than before.

This is not about how well it applies to the tailored
use in redhat's current scripts.
This is about creating a command which by doing only
a single thing (and to do so well) allows others
to utilize this.
