Using Data.Map.Map to sort gen outputs caused the ordering of certain fields inside the containers to change, breaking (at least) amazonka-emr-containers. The generator tries to calculate the set of derivable typeclasses through a Ptr, and takes a guess instead of looking up the actual pointed-to type.
I have spent a week and a half trying to make this work, and have decided to give up. More fundamental changes are needed, and they can be done after 2.0. The bug is still present, but the relative ordering of StructF vs Ptr versions of ShapeF within a HashMap hasn't triggered any broken service bindings... yet.
