Please clarify this. Users on older mysql will hit connection error immediately after upgrading to 8.6. So saying "their software could continue to work" is misleading. Their PHP code must be modified before upgrading - turning PDO::ATTR_PERSISTENT to false or removing it entirely. And only after that it would continue to work.
