Submenus through chain loading. Any drawbacks?

That is as good a method as any. The reason I've got it all in one file in the example is that it is easier to copy and paste when I need to update the example. Using multiple files is more modular, and absolutely a Good Thing™. I actually had my menus setup in multiple files, and then slowly combined them into a single one as I learned more about how to do things. What works for you is all dependent on your use-case.
