I am often times using that roadmap not only as way of visualizing the data but as the principal tool in which I can see all my projects and products at once, gain insight into the global picture of the work that is being done and then changing strategy when it makes sense. In this context, not showing all my features and releases by default does not make sense. Give me the option to have a roadmap show all elements (initiatives, goals, features, releases) by default so I dont have to go through the extra step of adding newly created elements.
