I have to admit I don't entirely understand this constraint.  CentOS 7 
is in support until 2024.  I would think RHEL 7's timeline is similar or 
even longer.  If Python 2 is going out of support in 2020, does that 
mean there will be no supported Python on CentOS for the last four years 
of its lifecycle?

In fact, the more I think about this the more I feel like there's a 
fundamental problem with the way we're handling this transition.  We're 
not the only ones who are going to feel the pain of having disjoint 
Python releases from 7 to 8.  Anyone running a Python application now 
gets to not only do a major OS upgrade, but also a major Python upgrade. 
  Sure, it's worse for us because we need to support EL 8 at release, 
but _everyone_ is going to feel some variation on this pain as they move 
forward.

I realize this is a discussion that's probably above my pay grade, but I 
feel I would be remiss if I didn't point out that our Python support 
strategy seems very flawed.

Indeed.  This sounds like a pub track discussion if I ever heard one. :-)
