@ehelms, can we eliminate :limit and :offset and just have :page and :per_page, at least for Foreman controllers.  I don't see a benefit of including :limit, :offset in the output, especially if the parameters can't be used for input.  Likewise, I don't expect Katello to output :page and :per_page if these params are not used as input.  I don't think that every controller in Foreman/Katello needs the exact same metadata.
