I'm not exactly sure what typemask= does, but by
looking at qgis/src/plugins/grass/qgsgrassmodule.cpp
it seems that it can only be one of point,line,area.

note the boundaries themselves are not acted upon,
and v.centroids is a simple wrapper around 
 v.category option=add type=area

might be expanded with "... to create areas"
