Hi there -- this is failing some specific rubocop rules, and it isn't actually being used anywhere. We have been very deliberate about not trying to parse the current state of the firewall, and instead rely on our own rules file that we build, when checking if things have changed and we need to re-run the rule file against the firewall. I'm not sure this kind of state-check method is something I want to include.

If you'd like to re-open as a passing PR, and want to further discuss the need for this method, I'd be more than glad to do so. I'm open to changes/improvements, but without a Windows-knowledgeable maintainer, I'm reticent to accept contributions like this. Thank you!
