I couldn't help but noticing that there are several places in GWT that perform logical aggregations, but don't expose the aggregated elements using Iterable (or List!). The two examples off the top of my head are IndexedPanel and ListBox, though I'm sure there are more.
IndexedPanel could just implement List<Widget> (or at the very least Iterable<Widget>). Similarly ListBox could specify ListBox.Item as a formal subclass, and implement List<Item>. Presumably there are others, but I generally see lots of value in tightly integrating with Collections (or at the very least Iterable), as it makes it trivial for Java users to consume new classes and constructs using know techniques, rather than having to research in each specific instance what the relevant method names are for performing manual iteration.
