At this point in time, I don't think producing SERPs like Google is a good thing. They are very unstable, solid aged sites getting tossed to the back to make room for junk.

If they produce the same results as Google, then there is no point in using Bing.

I have not noticed the keyword domain pruning. I have several keyword domains that are unique content rich that are doing fine.
