[Haskell-cafe] Package documentation complaints -- and a suggestion

The package summary is "Type-safe ADT-database mapping library.", which 
gives some idea about what it does.

In my experience, any package that starts its source files with

    {-# LANGUAGE GADTs, TypeFamilies, ExistentialQuantification, StandaloneDeriving, TypeSynonymInstances, MultiParamTypeClasses, FunctionalDependencies, FlexibleInstances, FlexibleContexts, OverlappingInstances, ScopedTypeVariables, GeneralizedNewtypeDeriving, UndecidableInstances, EmptyDataDecls #-}

is probably an experiment in what is possible, rather than a 
production-friendly library.

Many people upload experimental packages to Hackage so that they can be used 
by other interested people, even though the packages are not ready/intended 
for mass consumption. A lack of documentation in such cases is 

I wonder if it would be worth giving package uploaders control over whether 
their packages are shown on the package list? Packages can be manually 
hidden by emailing an admin, but that's a lot of trouble.
