that reminds me - I have a pbr patch I owe you guys...

But these aren't concerns specific to oslo code--they are the same questions that must be answered for every change in the code or dependencies.
> My (limited) understanding of the oslo config library is that there isn't a good migration path for existing deployments to move from the current config format to the format required by oslo config. This would need to be written in Swift, including config translators, so that both formats could be used, and I haven't seen yet a compelling benefit in oslo config that would adequately justify such a large change in the Swift codebase.
