It might be simpler to model this as a struct; there's no real reason to push
things through getters and setters into private variables if all you're doing is
passing two values around.

+    public:
+        PolicyOverrides()
+            : m_grantUniversalAccess(false)
+            , m_enforceFilePathSeparation(false)
+        {
+        }
+
+        PolicyOverrides(bool grantUniversalAccess, bool enforceFilePathSeparation)
+            : m_grantUniversalAccess(grantUniversalAccess)
+            , m_enforceFilePathSeparation(enforceFilePathSeparation)
+        {
+        }
+
+        // Mirrors what SecurityOrigin::grantUniversalAccess() grants.
+        bool grantUniversalAccess() const { return m_grantUniversalAccess; }

These both sound a bit strange. Perhaps "doesGrantUniversalAccess"? Without the
"does" it sounds like an action rather than a getter.

+
+    private:
+        bool m_grantUniversalAccess;
+        bool m_enforceFilePathSeparation;
+    };
+
+    // Return the origin policy overrides of this origin.
+    PolicyOverrides policyOverrides() const;
+
+    // Apply the overrides to this origin. Overrides that
+    // are set will be enabled, those that aren't will be
+    // cleared.
+    void applyPolicyOverrides(const PolicyOverrides&);

 private:
     SecurityOrigin();
     explicit SecurityOrigin(const KURL&);
