Shapefiles do not have the concept of plain linestrings or plain polygons, the have just one type that can contain both multiple and simple geometries, but there is no way to tell what is actually stored (unless, of course, one does not try to read the entire shapefile just to determine that information, which would be prohibitively expensive). So the only safe approach is to always use multi geometries no matter what.
