ext3 with ordered data writes has performance nearly up to the level of the fast-and-loose writeback mode for most workloads, and still avoids ever exposing stale disk blocks after a crash.
Sure, it's a tradeoff, but there are positions between the two extremes (totally unordered data writes, and totally journaled data writes) which offer a good compromise here.
