FWIW this appears to be due to FreeBSD's zfs support not supporting POSIX acl's.

https://docs.ansible.com/ansible-core/2.16/playbook_guide/playbooks_privilege_escalation.html#risks-of-becoming-an-unprivileged-user

Although the Solaris ZFS filesystem has filesystem ACLs, the ACLs are not POSIX.1e filesystem acls (they are NFSv4 ACLs instead). Ansible cannot use these ACLs to manage its temp file permissions so you may have to resort to the world_readable_temp option if the remote machines use ZFS.
