You're a bit late on this. :)
So what I did these last months (year?) in several project, is to check
at gate time the configuration file that is automatically generated
against what's in the patches.
That turned out to be a real problem because sometimes some options
changes from the eternal module we rely on (e.g. keystone authtoken or
oslo.messaging). In the end many projects (like Nova) disabled this
check altogether, and therefore removed the generated configuration file
From the git repository.

Because there's no way to automatically generate several configuration
files with each its own set of options using oslo.config.

Glance is (one of?) the last project in OpenStack to manually write its
sample configuration file, which are not up to date obviously.

So really this is mainly about following what every other projects did
the last year(s).
