It's nice to see this!

What strikes me immediately is that I can easily understand your Emacs
config, because configuration via Scheme records is so consistent and
uniform.  I can't usually say that about Emacs init files.

Granted, it does take a long time to get used to the format coming from
Elisp.  (And the import function isn't perfect.)

After thinking about what Ludo' said, I'm exploring the possibility of
removing the `configured-packages' fields and `emacs-package' record
type from the core `home-emacs-service-type'.

I could then put this functionality (~1300 lines) in a
`home-emacs-package-configuration-service-type' that extends the Emacs
home service.  That could go in a separate channel somewhere, but if it
is upstreamed then we can create a de facto standard that encourages
innovation and collaboration.

A bit of control over how the final serialized Elisp is formatted would
be lost by taking the package configuration functionality out of the
core Emacs home service, but it is not very significant (especially
considering that the point of using the feature would be to configure
Emacs in Scheme).  And it seems like there would be benefits to a
modularized approach from usability and implementation standpoints.

Anyway, thanks for testing!
