I agree that it's bad advice, since it assumes the only reason to use
Guile is to hack on Guix. I also think it's not necessary, since
‘.dir-locals.el’ in the Guix root should be taking care of this for you
already. I don't use the manual addition to ‘load-path’ you quote above,
and Geiser seems to work fine (within the bounds of Geiser's definition
of “fine”, anyway).

The downside of using dir-locals is that Emacs yells quite loudly about
unsafe variables being set. Another option may be direnv or bufenv? I
haven't tried them myself, but have heard good things.
