That one could be topology.ToTopoGeom (name can change):

The ToTopoGeom I had in mind would not throw an error but rather
add the missing pieces in that case. That way you would not even
need to add the components but could simply dump in all the final
geoms. We may think about adding a parameter to request an error 
rather than a silent addition.
