Using new export GLTF edges functionality

Would an approach like this work?

// 1) Read STEP into an XDE document
    Handle(TDocStd_Document) doc = new TDocStd_Document("XmlOcaf");
    STEPCAFControl_Reader reader;
    reader.SetDocument(doc);
    if (reader.ReadFile(stepFile)    != IFSelect_RetDone ||
        !reader.Transfer(doc)) {
        std::cerr << "ERROR: cannot load STEP file\n";
        return 1;
    }

    // 2) Get top-level shapes
    Handle(XCAFDoc_ShapeTool) shapeTool =
        XCAFDoc_DocumentTool::ShapeTool(doc->Main());
    TDF_LabelSequence rootShapes;
    shapeTool->GetFreeShapes(rootShapes);

    // 3) Mesh each shape (so triangles exist) and extract _all_ edges
    TopoDS_Compound edgeCompound;
    BRep_Builder builder;
    builder.MakeCompound(edgeCompound);

    for (Standard_Integer i = 1; i <= rootShapes.Length(); ++i) {
        TDF_Label lbl = rootShapes.Value(i);
        TopoDS_Shape shape = shapeTool->GetShape(lbl);

        // ensure triangulation
        BRepMesh_IncrementalMesh mesh(shape, 1e-2);

        // iterate _every_ edge and add to compound
        for (TopExp_Explorer exp(shape, TopAbs_EDGE); exp.More(); exp.Next()) {
            TopoDS_Edge edge = TopoDS::Edge(exp.Current());
            builder.Add(edgeCompound, edge);
        }
    }

    // 4) Add that compound as a new “free” shape
    TDF_Label edgesLabel = shapeTool->NewShape();
    shapeTool->SetShape(edgesLabel, edgeCompound);
    rootShapes.Append(edgesLabel);

    // 5) Export original shapes + our edge compound
    RWGltf_CafWriter writer(gltfFile, false);
    writer.Perform(
      doc,
      rootShapes,      // labels to export
      nullptr,         // no label-filter
      TColStd_IndexedDataMapOfStringString(), 
      Message_ProgressRange()
    );
