The Titus Revit models have been optimized to show all the basic information that the engineer needs without weighing down the model. There is a careful balance between providing information and making the file size so large that it hampers performance of the software. Revit and related 3rd party applications require the model to pass information to them to fully utilize their capabilities. Another benefit to the official Titus Revit models is that we created the models with shared parameters in mind.
