I want to interject here and mention that the Oslo team actually 
differentiates between things named oslo* and things not named oslo that 
are maintained by the Oslo team. The former are for OpenStack-specific 
logic and are not necessarily designed for broader use. The latter are 
intended as general purpose libraries to be used outside of OpenStack.

This obviously does not help here at all since it just muddies the water 
about what is and is not "for OpenStack", but I think it's important to 
note that this is not an either-or question for Oslo.
