That was a bad idea. Unless you want to reinforce the fact that
Python 3 is an agility killer. .5 ;)
There's release meta data to signal Python 3 compatibility.

Let's keep master stable. Maybe someone will want to
add features before the Python 3 support is stable.
I don't want to hold 4.1 hostage either.
I suggest breaking the Python 3 work into increments
that can each be introduced without sacrificing stability.
The first increment could provide Python 3 support
without any conversion or compatibility support. This is
something you could probably achieve pretty quickly and
would allow you meet your immediate goals.

Yes. It was predicated on a stable 4.0 release that had
very little in it beyond the split into separate packages.
It was intended to help people start transitioning
from ZODB3 to ZODB, but that can't happen until ZODB is
