We need a way to reference a client side rendered child (inner) widget without the need to hold a reference to it from the parent...
Because holding a reference to a inner widgets requires to listen to its lifecycle events to prevent memory leaks (when holding a direct reference to the widget), or to invalidate the string ID (if that is stored) if the inner widget gets destroyed.
When there would be a way to give a name/id at render time, the inner widget could be easily be referenced later with this.getWidget("widgetID")
The this.getElId('foo') method would be used to generate the fully qualified DOM element ID for the newly rendered component that is then appended to the parent.

Something like that would do it (probably):
