from an engineers prospective,  this renumbering hurts engineering  
troubleshooting before product release when you have multiple  
development releases.

But is a boon after the fact on a production run, for service issues,  
MAKE SURE that the boards have VERY clear revision numbers  in copper  
if posable too :-)


I have had people reworking boards replace the wrong component because  
of a revision mistranslation.
