Why setup_navigation_region needs a policy

This tool creates and inserts a new NavigationRegion node with associated mesh data into the Godot scene tree. This is a reversible modification (nodes can be deleted/undone), making it Write category. Severity is high because malicious use could corrupt game navigation logic, add unwanted geometry, or degrade performance by flooding the scene with navigation regions.

From the tool's definition Tool name 'setup_navigation_region' and description 'Add a NavigationRegion3D/2D with a NavigationMesh to the scene' indicate creation of a new scene component.
