i feel like this may actually be a good talking point when doing a multi-profile compliance demo. for cloud instances, the host-based firewall functionality is taken up by security group rules, so linux cloud images often do not have firewalld installed on purpose. talking about this could lead to a discussion about how specific controls in the compliance as code roles can be enabled or disabled as desired, and the extra_vars used in the setup could be shown as an example of how to do this.
