It looks like the logger returned by oslo.log does include the
values in the "extra" section but the others do not because the
code to introduce the values isn't invoked, just as when I run the
script.

Maybe. oslo.log has several dependencies that may also need to be
updated. Those should be backwards-compatible, but the configuration
you would end up with is not something we have ever tested. I'm also not
sure how you would get the right Ubuntu packages in place. Someone on
the openstack-operators mailing list might be able to help with that.

The releases web site (https://releases.openstack.org) documents the
versions of all of the components released for each series.

3.34.0 is a queens series release, which makes it more likely that more
other dependencies would need to be updated. Even backporting the
changes to the Ocata branch and releasing it from there would require
updating several other libraries.

Are you using packages from Canonical, or are you building them
yourself?
