Okay, thanks for this explanation.

Keystone team, this does not feel well documented. Let's come up with a
plan for further explaining that in the docs.

Good news, we have a new floating TOC and version labels that helps us go
towards documenting all versions on the reference page as well. See
http://api.openstack.org/api-ref.html.

Ideally when you have ideas and needs like this you'll log a bug or
blueprint at http://bugs.launchpad.net/openstack-api-site.
