Regardless of when the first alpha happens, I'll be promoting the hell
out of it, begging for feedback on any of these changes that are
available by then (which should be quite a few, given the preceding
PyCon US sprints).
If you can show me people who use the alphas who want them earlier,
I'll consider it. So far the only person who's said they want them
is you, and IIUC you won't be a consumer of the alpha per se.
