Is this PoC still going on? Is the branch still needed? The branch has been inactive since January and we are finding that patches against this branch don't pass zuul tests:
https://review.opendev.org/#/c/678144/. If the branch is still being used, the team working on it should fix it so tests pass. If it is not used, let's remove it. If I don't hear back from anyone having interest in maintaining this branch by September 6th, I will go ahead and remove it.
