includes are a simple way to do blending of HTML and Dojo components, though not as complex as the modification syntax, includes provide a simpler mechanism to change the UI.
One use case for the include functionality is delayed loading of content until needed. Take the example where you have a multiple screen application using a stack container. As a developer I would want to delay load the content of the second and third screens until it is needed. This will decrease startup time and increase perceived performance of the application.
