Handling arcs in an analytic way is somewhat difficult so almost everyone simply approximate arcs with lines (just like Kicad). The `obvious' solution is using NURBS (the only ones actually representing *exactly* conical sections, Bezier and csplines are only approximating them) but I think that would be overkill...
