   // Called by the shell once an instance for this application has been created.

-  //  connector
-  //    An interface back to the shell by which new connections may be
-  //    established.
-  //
   //  identity
   //    The identity of this instance in the shell. Includes:
   //    * The resolved name used in the connection request that resulted in this
   //      instance being initialized.
   //    * The user associated with this instance in the shell. This will never
   //      be kInheritUserID.
   //    * The instance group this instance belongs to.
   //
   //  id
   //    A unique identifier used by the shell to identify this instance.

+  // Response parameters:
+  //
+  //  connector_request
+  //    An optional Connector request for the shell to bind, allowing the
+  //    initialized client to connect to others.

Why optional?

+  //
+  Initialize(Identity identity, uint32 id) => (Connector&? connector_request);
 
   // Called when another application attempts to open a connection to this
   // application. An application implements this method to complete the exchange
   // of interface implementations with the remote application. See also
   // documentation in shell.mojom for Connect(). The application originating
   // the request is referred to as the "source" and the one receiving the
   // "target".
