Comment(by lrssvt):

 Replying to [comment:3 strk]:
 > I'd pick 4. (Add a single node to the topology, return an EMPTY
 TopoGeometry)
 yes! it is probably not a bug!

 <future_development>
 you have to understand what the end user wants. In this direction, we can
 think of a GUI (like qgis plugin) in the future. Possibly with the
 addition of creating topologies for two related geometries (for example
 line and polygon), create rules and set the ranks!
 </future_development>
