I mentioned this in another response:

> Our primary goal with the WiX Toolset was to provide access to the full power of the Windows Installer. Given the adoption by extremely large software projects, I think we've done pretty well toward that goal. We're slowly turning our attention to simplifying the toolset to make it easier to use for simpler projects. But that's only been a focus for the last couple of years, so not a lot has come about, yet. But the Files element is a huge upgrade.

There is definitely more we can do to make simpler things simpler. :)
