It may have had to do with timing. If no one was using the library, yet,
we may have decided to make a different set of changes there to support
both behaviors. It looks like that work stalled.

This change looks like it is related:
https://review.openstack.org/#/c/136842/ but it doesn't directly address
the issue of logging to /dev/log instead of the daemon.

Are you asking whether the code already works, or whether patches would
be accepted to make it work?

Typically it does not. The incubator is for code *before* it becomes a
library. After graduation, the incubated version is meant to be deleted.
The log library graduation got stuck on some other work early this
cycle, and so that part of the process was delayed. For more on how the
incubator works, see
http://specs.openstack.org/openstack/oslo-specs/specs/policy/incubator.html

I don't see a patch submitted to make that change.
