It has been removed, as documented in History9.htm:

     PDF interpreter - remove the PDFDontUseObjectNum switch

     This was implemented to allow us to restore the default behaviour if
     it caused problems. No real problems reported, so lets get rid of
     (yet another) of our many, many command line switches.

The fonts can't realistically be described as duplicates, if they have 
different object numbers. Or if they are then the original PDF file (this 
only works with PDF input) was poorly constructed. Using this option isn't 
really sensible, it was only ever present in case the Font numbering usage 
went awry. Consider creating the original PDF files more efficiently instead.

I'll discuss it with the other developers but I am not inclined to restore 
this. Obviously if you feel its important you can revert the change locally.
