Yup, you can access it this way, but this means passing around 2 different objects (InstallConfig and InstallScript) to be able to access the InstallConfigParams data while you fill the InstallConfig object. When I first looked at that code, I was actually very confused to find no link at all in the API between OsinfoInstallConfig and OsinfoInstallConfigParams, contrary to what their very similar names could imply.

It's currently only tied to an OsinfoInstallConfigParams instance (which indeed indirectly links it to an InstallScript instance in the current code). But I'm fine with not adding this property until a clear need for it appears, if ever.
