If we did that then every package would depend on haskell2010, which is
fine until haskell2013 comes along and they all need to be changed (or
miss out on any improvements that were made).

Even the really stable modules change, incidentally. For example, since
Haskell 2010, the Show superclass of Prelude.Num was removed, Prelude no
longer exports catch, and Data.List gained a function dropWhileEnd.
