Open Stack

Guess I was wrong again.

https://review.openstack.org/30250
https://review.openstack.org/#/c/30094/

These two patches will fix the problem.
Aaron, I'm talking with amotoki on IRC now about this topic.

The only solution to what you propose is to merge a patch which replaces
all capital group name references and also bumps oslo.config to 1.2.0
together.

Ping me anytime if you have questions.

Thanks
