I would love to have oslo.config more widely adopted outside of OpenStack. At the same time, it has a very opinionated way of managing config than most applications need, so I can understand why it might not be.

When I did the original analysis for breaking oslo-incubator up into separate libraries, I had to balance the work to create and manage individual libraries and their cross-dependencies with the desire to have everything nice and neat. The utils library ended up as a catch all for things that didnâ??t seem reusable outside of OpenStack so that at a time before all of our release automation was in place the team only had to manage ~30 libraries instead of ~50. Of course that can evolve, if someone feels strongly enough to do the work. Itâ??s certainly easier today than it was back then.

The log library is there to make it simple for all OpenStack services to configure their logging in the same way. Itâ??s glue between oslo.config and Pythonâ??s logging module. Similarly, the i18n library is the glue between oslo.config and Pythonâ??s gettext module.
The hint is in their names. The â??oslo" prefix was reserved for libraries that are more likely to be seen as only useful within OpenStack. In a project as large as OpenStack, thereâ??s a fair amount of code that can be reused but that wouldnâ??t make sense for use in any other code bases. For libraries that we thought would be useful by other communities, we chose more generic names.
