Hi,

There are valid use cases for uninstalling Guix: 
- On a Trisquel VM I use Guix to add matterbridge to it with guix pack.
  Once the tarball is done with guix pack I remove Guix and install the
  pack to limit the attack surface. To do the updates I install Guix
  back and re-do a tarball.
- On some machines I sometimes need Guix but when I don't need it
  anymore I tend to remove it not to have to maintain too much software
  (having to run guix pull when you don't use Guix is probably not a
  good idea).

So I use a standalone script I did for that, but the patch in this bug
report is more complete than my script, so I should probably find the
time to pick up that work.

Denis.
