Why do you mention "part of a lineal", if the signature returns
a full TopoGeometry (by id) ? What's a "topogeom name" ?

The functions you suggest seem very specific to your need, not sure it
would make sense to have them in core. I think we do have a function
to get a list of primitives from a TopoGeometry. Maybe a generic missing
function is one to get a list of TopoGeometry from primitives.
