Ray, I work for a contract manufacturer specializing in small - medium production volumes. Fiducials are more than just handy! The Pick & Place equipment uses fiducials to identify board location and fine pitch part location.
If they're not present we have to jump through hoops to get parts placed correctly. As a result placement accuracy suffers which can force re-work. This means we have to charge you more!

Are they necessary or just something that may come in handy? Might a board assembler tell you he can't pick and place if you don't have them? My board has 4.9mil traces and spaces and many of my components are 10mils apart.
