Web server and DNS may be hijacked and return the wrong Dat key. This new caching method allows for name resolution caching to grow linearly as confidence in the returned result increases over time. E.g. if a name was first resolved three days ago, it can be cached for up to six additional days if we're confident in the resolver result. After two weeks, the name can be cached for four weeks and so on. Domain owner still controls maximum caching time with TTL. Increases performance and privacy while making clients less susceptible to centralized/decentralized service disruptions (such as a DDoS or a server running out of memory.) Reduces dependency on servers.

I've written an article, Well-Known URI vs DNS-SD for routing distributed web service discovery around internet censorship (and disruptions), that has some more context on why these changes are necessary.
