No, not at all -- at least not for nightly snapshots, good old tarballs is
the best way to distribute these. Installers makes better sense for
releases though, providing a one(2?)-click package for people to
get started with GHC, i.e., not requiring users to have misc utils
(e.g., tar/winzip) installed on their machines.
Writing a Haskell program that manipulates your file type associations
wouldn't be hard.
