Why delete_firewall_zone is rated Critical

Deleting a firewall zone removes network segmentation rules and security boundaries irreversibly. This is a destructive action with significant blast radius in a security context, warranting high severity.
From the tool's definition Tool name 'delete_firewall_zone' explicitly indicates deletion of a firewall zone, which is an irreversible operation that cannot be undone. The 'delete' action is characteristic of Destructive category tools.
