KiCad had no support for copper arcs at all about one year ago! For your microphone there is a simple solution -- ad a copper arc in PCB editor after you had positioned the footprint with missing arc. I still wonder why KiCad has avoided copper arcs so long, and why PCB avoided copper arcs in footprints. I think gerber formats supports arcs. One problem with arcs is: If we have stretched arcs, DRC may be much more difficult -- I have to admit that I have no idea how to test stretched arcs for intersection with other elements (fast). Another problem can be autorouting when we have arcs on the board -- for geometrical and topological routers there should be some difficulties.
