Oh, come on, Nick, that's just silly. setuptools was included in stdlib
for a short while, so the above is simply wrong. Eggs are the most
widely used binary distribution format for Python package on PyPI:

# wc *files.csv
  25585   25598 1431013 2013-02-19-egg-files.csv
   4619    4640  236694 2013-02-19-exe-files.csv
    254     255   13402 2013-02-19-msi-files.csv
 104691  104853 5251962 2013-02-19-tar-gz-files.csv
     24      24    1221 2013-02-19-whl-files.csv
  17937   18022  905913 2013-02-19-zip-files.csv
 153110  153392 7840205 total

(based on todays PyPI stats)

It doesn't really help ignoring realities... and I'm saying
that as one of the core devs who got setuptools kicked out of
the stdlib again.
