[wix-users] How do I handle SetupFilesCleanup and SetupFiles Extract in Wix

Think upgrading completely to 4.0 is no good idea as this is under heavy
development and think not thought to use for production code.

To be clear:
ISSetupFilesExtract - This is used by InstallShield for following Use Case:
When a Custom Action needs to run an executable helper file which should
not be installed: Then during Install Runtime ISSetupFilesExtract
temporarily extracts this executable helper file (and if needed additional
files), a CA can run that executable and afterwards before terminating the
installation these temporary helper files get removed by the
ISSetupFilesCleanup AFAIR.

This use case is in my eyes rarely used. A more frequent use case is to
call an executable which is also installed and therefore such a temporary
extraction is not needed
