Hackage has limited support for distro maintainers to state which
packages are available on the distribution.  Last I checked, it required
distro maintainers to keep a text file somewhere up to date.

Note that not all distributions bother (in particular none of us
involved with packaging Haskell packages for Gentoo can be bothered;
we're slowly cutting back into only keeping packages that will actually
be used rather than all and sundry), and even those that do might just
list what's in the official repository (I think arch does this).  Even
then, Don Steward has a policy of packaging all and sundry for Arch (at
least in the unofficial repository; this includes packages such as
haskell-updater that are written for Gentoo).

As for why using your distro package manager for Haskell packages is
