Bob the Builder produced them. Joe User uses them.
But you are right, there is indeed an intermediate role, the person who
downloads and installs the binary package. This does not necessarily
involve any building, but still requires a minor degree of knowledge
of the packaging scheme.
However, in Cabal, there are many different possible binary packaging
schemes. Various people will use RPM, .deb, .msi, apt-get, BSD ports,
and so on. Essentially, we assume that the person who downloads and
installs one of these formats is competent with their chosen mechanism.
They just use whatever is standard for their platform. So it seems
fair to characterise that role as Joe User, since we don't really
expect any familiarity with Cabal. Indeed, such a person does not
(knowingly) use Cabal at all!
However Cabal does address the person who /creates/ an RPM, .msi, etc,
who needs have a documented protocol for building, installing, and
registering Haskell code. Roland, Willie, etc, embed that knowledge
into the binary package, so the final user, Joe, does not need to
think about it.

You are almost certainly Joe, if your ideal world is to download a
.msi InstallShield binary package and press the button.
