It's not clear when you should 'refresh' the civicrm.settings.php file
Occasionally, there are changes to the civicrm.settings.php file. It doesn't feel clear to me, how that is communicated (i.e. how I'd know I should refresh my file). While it is technically listed in the full release notes, sometimes it can be buried in the miscellany section. Would it make sense to add a tip to the upgrade documentation: https://docs.civicrm.org/sysadmin/en/latest/upgrade/ along the lines that you should check for changes to the settings file when running an upgrade?
