Could work, I'll see what I can do.  But first I'd like to know how to
actually add this to Guix! :)
Rebuild the world on core-updates or is there another way?

I could be misunderstanding you.  The keys are self-documented like all
key arguments.  From any REPL / text editor, you would typically "show
the procedure arguments" to see what's available.  In Emacs/Geiser,
you can use Eldoc or completion to access the full list of key parameters.
