I think you have it exactly backwards. Most ImGUI use cases are extremely complex UIs and that's where they excel.
One of the most complex apps out there, Unity, is entirely ImGUI based for the app itself and often has 1000s of controls visible. Going though the screenshots of typical ImGUI usage most of them are on the complex side.
