An antenna might also want t= o force a cleared solder mask area, again requiring trickery (zero width co= pper in pads has been used before, with a wide mask openning IIRC).

Longer term, it would be nice t= o allow more flexibility of what items can be used in a footprint, and what= "layers" can be used.
