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!

I was reading about fiducials in J-STD-013.  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.
