Hmmm.  We had requests to express plated slots in this group.  If
somebody defines an extra via layer for slots, and draws polygons or
traces on it, the exporter should recognise that and produce a gerber
instead of a drill file.  The rest is negotiation with the vendor.

PCB will be able to check the connectivity by the via connectivity
attributes.

I'd love to draw square polygons (or better traces without rounded caps)
on a via layer and export to gds2 instead or gerber.
