pcbs mating with old fashioned card edge connectors had gold plating on
the copper in the connector region only, or gold on nickel on copper.

I have never seen a separate gold plate layer in a PCB layout
program. Has anybody else? Are there situations where you wouldn't
plate certain areas of surface copper (if you are plating)? Can PCB
fabs even selectively plate gold onto certain areas of the board?
