I'm not %100 sure that's really an accurate assessment of the slow 
uptake in Python3.  Regardless, the clock is ticking on the 2.x codebase 
as it is reaching EOL status in 2020:

Hopefully a solid deadline (which has already been pushed back) will 
motivate developers to accelerate the task of migrating to py3 sooner 
rather than later.
