<p>I think the set_default_request_format would be better applied to every api method, but you only have it for a few (e.g. before_action :set_default_request_format, :except => [:create, :update, :delete]). Can you talk more about that?</p>

<p>Yes, that's also intentional. On the one hand, I only wanted to include those methods for which we have some test coverage. On the other hand, some of those methods return plain text, rather than XML. I felt like overriding request.format could potentially introduce some havor in the future, so I deliberately excluded those methods which are not in scope right now.</p>
