To me this seems information to put in a comment next to the input list
(and next to python-zeroconf-0.33). Also, I recommend removing the pip
downloading code to be 100% sure it won't be run.

There are bugs in the python-zeroconf@0.33 that have been fixed in
python-zeroconf@0.38.1.  The readme in
https://github.com/jstasiak/python-zeroconf mentions a few fixed bugs
that seem rather subtle.

So as-is, we would be distributing an octoprint with a known-buggy
depdendency with known fixes.  Though neither is changing to the new
zeroconf an option (unless changes are made to octoprint) as-is because
the new zeroconf is apparently incompatible.

Maxime.
