personally I've stopped using Ansible some time ago and switched to judo ( https://github.com/rollcat/judo ) and pssh with a custom wrapper script. But my tasks/playbooks are rather simple
Edit: The earlier linked OpenBSD py-parallel-ssh port seems to be something different - the original current code of #pssh is this: https://github.com/lilydjwg/pssh, #FreeBSD has this port: https://www.freshports.org/security/pssh/
