Autodesk is just a company will not really want to improve their product. Trunking is a very important component in electrical engineering. I can tell you why people are not willing to use revit, this is the most reason I heard, no in revit.
Electrical Trunking is a commonly used feature in electrical projects. Adding this feature to the software would be a great help and a more accurate representation of real-life electrical installations. As there's already a wall sweep tool for architecture, it would be relatively simple to transform or use it as a base for the Electrical Trunking.
