Also, if the network is not operational at the time you configure your interface, you don't notice duplicates, even if everybody carefully looks for them when bringing up or changing interfaces.
This is a rather common situation at meetings, where wireless cards are mis-configured, hubs have no power, some of the cables are broken, and people who are blissfully unaware of any address allocation procedure enter the room and instantly try to set up their machines. (And of course nobody had time to prepare a DHCP server.)
Thumbs up from me.
