Note that in part mode it appears that you can create a "default" representation for a part. You can see here the option to set the feature inclusion in a rep to default which implies that you may be able to add this rep to your start parts if required. You can name a rep "Default" when created with this default function to get what your user is looking for. You should test this in a start part to see if it functions as desired.
What type of non-assembly file are you referring to? In part mode simplified reps are available in Creo 10. They will be found in the view tab->view manager->simplified rep tab.
Or are you asking why in a part is the default rep not present? If this is the question, I don't know why a default rep is not present in a part. I suspect it is because it is not needed in the context of a part since all features are available when opening a part file and would serve as the basis for the creation of any new representations. In an assembly being able to revert to a "basis state" (default rep) was deemed important due to the potential inherent hierarchy and complexity in assemblies.
