Just noting that while I've closed this issue as fixed, I think we still have quite a bit of work to do to get our handling of these pre-init config settings to a place we're genuinely happy with (or as happy as backwards compatibility constraints permit).

However, the next step in that process is likely to involve at least myself, Victor & Eric getting together in person to discuss it at PyCon US (as I'm pretty sure we'll all be there this year), and deciding on how we'd like PEP 432 to look for Python 3.8.
