Dear maintainers of

Hi, Simon -
How did you come up with this list? It is missing the vast majority of users of Rank2Types.
Most people embed language pragmas directly into the source files that use them, so grepping .cabal files is going to massively undercount users of any given feature.
Based on repeated recent experience, I expect getting rid of Rank2Types to be another substantial source of make-work for library authors. The GHC upgrade path has been very bumpy indeed recently, and this seems assured to continue that unhappy trend. I respectfully request that you silently retain Rank2Types as a synonym for RankNTypes.
Thanks,
Bryan.
