So this - https://github.com/openstack/oslo.messaging/commit/bcb3b23b8f6e7d01e38fdc031982558711bb7586 was clearly a violation of our 1 cycle for deprecation of config options. I think that should be reverted, an oops release put out to fix it, and then deprecate for 1.6. If oslo libraries are going to include config options, they have to follow the same config deprecation as that's a contract that projects project up. Otherwise we need to rethink the ability for libraries to use oslo config (which, honestly is worth rethinking). -Sean -- Sean Dague http://dague.net
