You also lose the polygon material mapping if you're just going to have a surface (presumably generated from just SRTM data) with the generated texture draped over it. IMHO this is a huge benefit of what we have already, since that's what allows us to have things like amphibious aircraft, operate aircraft from roads (I'm thinking of the harrier, jaguar, air ambulance operations etc etc) and generally ensure a nice bumpy landing when you have to choose a field for your glider because you ran out of altitude before you made it back home. AFAIK this is something pretty unique to FlightGear - we should think very carefully before dropping it.
