Is teuthology-openstack still available

Hi, everyone. Is teuthology-openstack still used to do large scale testing nowadays? Recently, we are planning to use teuthology as the basis to build some large scale ceph testing infrastructure on top of our virtualization platform. And we thought teuthology-openstack is relatively suitable for our purpose. However, it seems that some of its code is still using the PY2 environment and hasn't been maintained for a while, which brought us to this question. Thanks:-)
