Some people might be quite excited by Milan's work on significant
performance improvements to the containers package...

Data.Map is the way it is for historical reasons. It needs a dedicated performance maintainer to do detailed benchmarking and static analysis.
I did quite a lot of benchmarking, strictness analysis and performance improvements to the containers package recently, see the draft of my paper http://fox.ucw.cz/papers/containers/containers.pdf. Next week I will start finalizing the patches and submit them. The 'not generating a worker/wrapper' issue is one of several on my radar, so this should be resolved.
