GRASS is not ArcGIS. So it doesn't have the same restrictions that ArcGIS does about points, lines, and polygons being in separate layers. Of course, YOU can make a vector file (i.e., layer) that is only points or lines or polygons, but you are not REQUIRED to do so. If you want to export vector objects from GRASS to shapefiles or something else, you can select only one feature type to export. GRASS also allows you to convert between vector types and converts from raster to vector.
Why is this a problem? I always was annoyed about the requirement of ArcView and ArcGIS to have only one feature type per shapefile.
