Usually the other programs have specific importers for other tools. It is unreasonable to expect a tool to support the formats of others for export. Even five figure professional tools only do those exports and then have separate importer plugins. For example Altium Designer recently added a functional kicad importer. But the DXF stuff? Excellent for integration with mechanical CAD tools and for use with RF simulators like CST or HFSS. QUCS Studio is the odd one out that they support importing kicad layout files into their EM simulator.
