In many cases it's not. In fact I've recently worked on several projects where the frontend is stupidly heavy for zero reason. Just sloppy or over engineered code. I know the full extent of the capabilities - one is just a corporate website with no interactivity. It's just dumb. The previous version was just simple static HTML; but as part of the "responsive design overhaul" it turned into this behemoth that makes several dozen requests to open the homepage. Nuts.
