The problem is not that tiles are interpreted as rectangular in the latitude-longitude system if interpreted cartesic, but instead that the tile grid is inconsistent even without the problems of representing spherical coordinates in a planar system. While what you describe are problems (e.g. I had to remove an airport located at one of the poles because it gave TerraGear a hard time wrapping it around the world), they do not apply for the specific bug mentioned here. BTW: The .btg.gz-files use geocentric cartesian coordinates, so that the earth is actually round and closed in the scenery.
