commit 6f35cc3fec480bc59b3f4911aeb731b43933acdc
Author: Paul Ramsey <pramsey at cleverelephant.ca>
Date:   Thu Nov 5 11:49:10 2020 -0800

    Swap axes that have 'Lat' in the first axis. Don't swap axes that are 'Easting' first. After that, believe the directionality provided and swap any 'north' axes. If you still don't know what to do, just leave the axes alone.
