I’ve seen some pretty feature rich PDFs - before WebGIS got really good, people would often disseminate digital maps and geographic reports via GeospatialPDF which is an extension for PDF. You can do all kinds of stuff in there related to measuring distances, coordinate transformations and zoom/pan around the maps. Some of these files would end up being >500MB. Probably still used quite a lot field work I imagine.
