Writing software that ignores explicit configuration directives is a    
great way to wind up with undebuggable software.  In a conflict, which
one wins?  In the case of duplicates, what else in the configuration is
unreliable and/or unintentional?

It's much safer to exit.  If you're concerned about outages, use --test 
before you make changes to the production service.
