Comment 24 for bug 1850977

Not sure whether removing files that came with distro packages is the best idea long term. I think a better option would be to drop in a custom rule that runs before the default ones. As usual ArchWiki has some examples: https://wiki.archlinux.org/index.php/Polkit#Administrator_identities

Specifically, if I'm reading this right, putting the following rule in /etc/polkit-1/rules.d/00-override.rules should be enough:

/* Always authenticate Admins by prompting for the root
 * password, similar to the rootpw option in sudo
 */
polkit.addAdminRule(function(action, subject) {
    return ["unix-user:root"];
});

Having this it's easy to build a package that can be later distributed to other workstations.
