[CentOS-devel] Why are Spacewalk packages removed from CentOS?

Hi, severals users of Spacewalk [1] reported that Spacewalk client tools are removed [2] from CentOS (they are present in RHEL).

It's about packages: rhn-check rhn-client-tools rhnlib rhnsd rhn-setup rhn-setup-gnome yum-rhn-plugin

I dig up in history [3] and find that the reason was probably reference to rhn.redhat.com. Since current Spacewalk (default) configuration should not hit rhn.redhat.com I'm curious if those packages can be put back to CentOS? Or is some other reason behind removal of those packages?
