I believe this is not meant to replace Ansible, but work like an "engine" that Ansible and other similar tools can run under the hood. This is quite low level code even for an everyday Python developer.
Ansible internally abstracts all its SSH bits into a 'connection plug-in', the initial goal is implementing another one of those. So with one or two extra lines in ansible.cfg you will get a much faster Ansible, with no other changes necessary.
I've no desire to replace Ansible, I'm just sick of wasting hours waiting for it to finish
