As mentioned in the cover letter for v4, octoprint hard-checks the
versions of its dependencies and uses pip to download new versions for
the packages it judges the version is incorrect. In the case of
zeroconf there is a notice in setup.py:

The author recognizes that octoprint is not so friendly to packagers:

I guess it would be better if Guix users install octoprint in its own
dedicated profile.
