@eric sorenson would it be acceptable if the information is displayed only in debug mode? I have PR ready to add the current taxonomies to the response headers. The response headers are printed in hammer debug mode. Advantage of this approach is that the taxonomies are displayed for each API subcall we do during the Hammer command execution.

This is what could be seen in the output for each request:

[DEBUG 2018-01-24 12:40:21 API] Response headers: {
                                 :date => "Wed, 24 Jan 2018 12:40:01 GMT",
                               :server => "Apache/2.4.6 (Red Hat Enterprise Linux)",
                      :foreman_version => "1.15.6.30",
                  :foreman_api_version => "2",
                 :current_organization => "1; Default Organization",
                     :current_location => "; ANY",
...

If this is okay, no changes in Hammer are needed and I'll switch the component to Foreman/API
