It exists only for py2/py3 compat. We do not need it any more. This will explicitly break Zuul v3 for python2, which is different than simply ceasing to test it and no longer declaring we support it. Since we're not testing it any longer, it's bound to degrade overtime without us noticing, so hopefully a clean and explicit break will prevent people from running under python2 and it working for a minute, then breaking later.
