The other thing is that latency is basically a given property in any system - as an app writer you have to live with it, there's not much you can do to improve it. Bandwidth on the other hand is a lot more engineerable, as it tends to be about batching things and you can batch in user-space too. Batching is often easier to do than getting good latencies. Then there's also the fact that the range of apps that care about bandwidth is a lot smaller than the range of apps which care about latencies. The default should help more apps - i.e. latencies.
