Thanks for the response. I think one of the things I was confused about was
that yes, the "average" user doesn't have to create packages, but can just
make manifests. There isn't much discussion of manifests in the
documentation, and I just missed it.

But manifests are required for me to use Guix. If my best option is running
`guix package -i emacs`, that's no advantage for me over `apt-get install
emacs`. Your mileage may differ; this is my opinion. I'm similarly not
installing GuixSD right now, but am using it on top of Ubuntu.
