I agree, that very well summarizes my motivation for adding it!

If you want ‘home-configuration.scm’ to refer to files in that path,
then GUIX_PACKAGE_PATH needs to be set in the environment of where ‘guix
home’ itself is running.  Like so:

  export GUIX_PACKAGE_PATH=/path/to/your/packages
  guix home container …

Alternatively, you can run:

  guix home container -L /path/to/your/packages …

HTH!
