[cctbxbb] Is there a schedule for the python3 migration or can cctbx.python already be built to be/use a python3 interpreter?

With DIALS we use python3 exclusively - have done so for a long while - everything we use from cctbx seems largely OK with this

Python2 is dead to me, and many other dials devs

All the best Graeme
