IMO, that class of users don't need anything beyond the packages bundled
with GHC anyway...

However, LYAH already directs such users to the platform as it states in
its introduction:

| What you need to dive in
| A text editor and a Haskell compiler. You probably already have your
| favorite text editor installed so we won't waste time on that. For the
| purposes of this tutorial we'll be using GHC, the most widely used
| Haskell compiler. 
| *The best way to get started is to download the Haskell Platform,*
| which is basically Haskell with batteries included.* 
| [...]

And here's what Bird's "Thinking Functionally with Haskell" has to say
about the HP:

| 1.5 The Haskell Platform
| If you visit the site www.haskell.org, you will see how to download
| The Haskell Platform. This is a large collection of tools and packages
| that can be used to run Haskell scripts. The platform comes in three
| versions, one for each of Windows, Mac and Linux. We deal only with
| the Windows version, the others being similar.

So I'm not too worried that newcomers following a guided course/tutorial
(such as LYAH or TFwH) won't be directed to the platform.
