I think they've served their purpose, and have now taken on a life of their own.
Thinking of fires, for example - these used to be a major hazard, but their now more or less a solved problem, and a lot has changed since the fire codes were written. Like, people don't smoke nearly as much any more, clothing and furniture is far less hazardous, and electrical appliances are lower power and safer now. These days, the only time people actually die in fires is when they are doing something hazardous and illegal anyway.
