Good point. In this case we could remove the -c flag for v.in.ogr in trunk and always convert simple feature polygons to topological areas. Supporting arguments would be that compared to GRASS 6, topology in GRASS 7 is more robust, uses less resources, cleaning functions are often faster, also use less resources, and vector topology including cleaning functions is according to the bug tracker bug-free, AFAICT.
