With current selinux-policy-37.22-1.fc37.noarch, and presumably any future update for Fedora 37, the user_namespace class is not available, so statements using it prevent the policy from being loaded. If a class is not defined in the base policy, any related permission is assumed to be enabled, so we can safely drop those.
