Nah, using Altium.  I have them set as "Standard (No BOM)" and it
appears they don't come out on Pick and Place when I do that.  Did not
realize until I saw it today, by accident; most of my boards have
fiducials "just in case" it goes to pick and place.  This particular
board will be, so I'm glad I caught it now--but now I need to check on
that on a bunch of prior designs...

They should definitely be in the PNP file.

If you're using PADS, I recommend adding them as non-ECO parts and
giving
them a prefix like 'FID' so they can be spotted easily.
