Re: [DISCUSS] Re-think CI strategy?

Not wanting to answer for Wes, but those are two sides of the same coin:
reducing CI overhead and complexity helps increase developer
productivity.  Reducing CI overhead is not a goal *in itself* (unless
there are money issues I don't know about) ;-)

The productivity cost of being Python 2-compatible is not very high
*currently* (since much of the cost is a sunk cost by now), but these
things all add up.  So at some point we should really drop Python 2.
Whether it's 2019 or 2020, I don't know and I don't get to decide.

However, anything later than 2020 is excessively conservative IMHO.
