RFC: include a cabal-install executable in future GHC releases

Hello,
My input is this: I think a lot of confusion stems from some
documentation that just needs to be cleared up.
I think that just cleaning up the pages so that:
* http://www.haskell.org/cabal has binaries for Tier 1 platforms: OS
X, Windows, FreeBSD i386/amd64, Linux i386/amd64. IMO, there should be
a clear 'Download pre-built binaries' on the immediate front page that
cannot be missed.
* http://www.haskell.org/ghc/download still points to the platform
for most users (i.e. the platform is more long-term stable/supported,)
but also mentions cabal install binaries. They can be linked to
directly from the subsection for each platform: "Download GHC 7.8.1
Mac OS X x86-64 - also download <latest cabal-install OS X build> from
here"
I personally think this would go a significant way to making it easier
for people to bootstrap environments. (IMO, both the GHC and Cabal
homepage could both do with a visual makeover as well, to make this
all the more apparent and easily accessible.)
As for cabal install binaries: I can easily provide dedicated hardware
(thanks to Rackspace) for Windows, FreeBSD or Linux build machines. I
also have a dedicated OS X machine in Oxford (thanks to Duncan) that
can be used to build binaries for OS X as well. So I can absolutely
provide resources for Cabal developers to build them if they'd like.
At least for T1 platforms.
As for shipping with GHC itself: this is technically possible, but
slightly annoying to implement, and it also makes the build processes
for a release slightly more annoying (which is mostly my problem.) But
it is all doable. However, keep in mind I *do not* maintain the binary
distributions for everything, nor do Cabal devs have access to all
hardware - so all people making upstream releases for their platforms
(i.e. Solaris, PowerPC, ARM/Linux, etc) must also package cabal
themselves. But perhaps that's not a huge deal.
I guess my vote on this is ultimately neutral. I think it can be fixed
by simply making the downloads more clear. Alternatively we can
package cabal-install. I'll leave the decision up to users at large
and their votes.
