As I understand the contribution process for Ansible core (github: ansible/ansible), someone needs to make a PR to add the changelog fragment to the devel branch. Once that is done, a PR to add the patch and the changelog fragment can be opened up against branches stable-2.8 and stable-2.9. Then it will go out in patch releases.
For the problem local to your server, you might try testing with the development version of Ansible. I think we allow easily specifying a custom virtualenv for inventory sources like this now.
