They were not (notably) touched in more than 3 years.
I doubt anybody is using them.
Also, nowadays we have contrib/rpm to build NetworkManager
packages for Fedora/RPM. We have copr, we have automated CI
in CentOS CI and beaker.
Also, nowadays it should be easy to spawn a a fedora image
in a container or tools like vagrant.
I think there are better alternatives. Drop the scripts.
