Note sure if this was directed to my comments about what Infra has done or if you mean to suggest this for Tripleo. In the Infra case we do not deploy openstack. We deploy a ton of software on top of OpenStack so OSA isn't relevant for our uses.

Then we updated our puppetry to pull hiera data out of there. This means that puppet and ansible read the same data sources which has made transitioning things easy for us.
