nokian  filed a deletion request for freecad-dxf :
The developer writes on github:
"The files in this repository are not needed anymore when using the
built-in DXF importer (default since FreeCAD 0.16). They are still
needed if you wish to use the legacy python importer (settable in
Edit-> Preferences -> Import/Export -> DXF) or if you wish to export
directly from the 3D model (exporting a Drawing page to DXF also
doesn't require these files)"
