Problem is that casting curved shapes into triangles, the way our Scenery is currently set up, results in a pretty high triangle count. A couple of months ago I've done a few tests: Compiling X-Plane's current layout of KSFO (being a prominent example), including all the yellow taxi lines, into a triangluated surface leads to approx. 50k triangles just for the pure airfield. Now add the effect which Ralf has been explaining on this page: http://www.custom-scenery.org/Triangle-Counts.272.0.html .... and we'll end up with a _much_ higher triangle count than we're used to. According to past experience with inserting OSM line data for the (major) roads I'd say that FlightGear is currently not ready for this representation of curved shapes - especially not for mainstream Scenery which is supposed to run on a wide range of hardware.
