Just a couple other data points:
      * 6.4 was never stable
      * 6.4.1 is not even marked stable in debian yet (only 6.2.2 is
        stable)
      * 6.4.1 was only marked stable in gentoo in March of this year
        (6.4.2 was marked stable in August)

It's true that packages could use an external compat Data.FiniteMap but
that causes problems too of course. The Cabal conditional configurations
feature is not available yet.
