Hi! This looks like a really nice script!
A while back, I wrote a bit of elisp that does some of the same stuff that your program does, but which is aimed at a workflow based on profiles rather than on `guix shell`, see [0]. I have previously used said script to set up directory-specific paths/environment variables, but currently I only use it to globally enable/disable certain profiles at runtime. Back when I wrote it, I was planning on rewriting it and integrating it into emacs-guix, but I never got around to it. In general, it would be nice to refactor it to use emacs-guix's `guix-repl' function rather than manually running shell commands. A caveat of my script: it sets the `load-path` variable, which is useful at times but greatly increases the foot-shoot-ability.
