We'll need to get some input from other distros and from deployers
before we decide on a timeline for dropping Python 2. For now, let's
focus on making Python 3 work. Then we can all rejoice while having the

Let's see what PTLs have to say about planning, but I think if not
Ocata then we'd want to set one for the P release. We're running
out of supported lifetime for Python 2.7.
