I think these are probably better called something like WindowManager and
WindowManagerClient.

I think there's probably a conflict right now due to other interfaces.

ViewManagerWM & ViewManagerWMClient are reasonable though.

+interface ViewManagerServiceDelegate {
+  // Asks the delegate to embed the url at the appropriate place.
+  Embed(string url, ServiceProvider&? service_provider);
+
+  // Called when an input event is received from the native system. It's
+  // expected the delegate will call DispatchInputEventToView().
+  OnViewInputEvent(mojo.Event event);
+};
+
+[Client=ViewManagerServiceDelegate]
+interface ViewManagerServiceDelegateClient {
+  // Dispatches the specified input event to the specified view.
+  DispatchInputEventToView(uint32 view_id, mojo.Event event);
+};
+
+}
