Right. The scripted patches work with older versions of tox as
well. They also have the benefit of only changing the environments into
which the new setting is injected, which means if you have a
py27-do-something-random environment it isn't going to suddenly start
using python 3 instead of python 2.7.

The thing we care about for the goal is ensuring that the required jobs
run under python 3.  Teams are, as always, completely free to choose
alternative implementations if they are willing to update the patches
(or write alternative ones).
