WiX toolset EXE Wrapper installer with no files - wix

Question

I have a simple working EXE wrapper in WIX but I don't like that I have to add at least one file for it to work and I can't seem to find a way to not add files to it, is it even possible?
<?xml version="1.0" encoding="UTF-8" ?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Product>
<Package Compressed="yes" InstallerVersion="301" />
<Media Id="1" Cabinet="media1.cab" EmbedCab="yes" />
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="MyProgramDir" Name="MyInstaller">
<Single unwanted dummy component here>
</Directory </Directory>
</Directory>
<Binary Id="MYEXE" SourceFile="Installer.exe" />
<CustomAction Id="RunInstaller" BinaryKey="MYEXE" ExeCommand="" Impersonate="no" Execute="deferred" Return="asyncNoWait" />
<InstallExecuteSequence>
<Custom Action="RunInstaller" Before="InstallFinalize">
NOT Installed
</Custom>
</InstallExecuteSequence>
<Feature Id="ProductFeature" Level="1">
<Single unwanted dummy component ref here>
</Feature>
</Product>
</Wix>

You don't have to have atleast one file (although the scenarios where you don't have any files are very, very rare) you do have to have atleast 1 component and that component has to have a key. The key can be a file, registry entry or by default directory.
The old saying is that installers is more then just copying files but generally they always include atleast copying a file or two.
