Required params at the top level namespace, is this possible?

[ggwc82]

My code is currently like this:

    namespace :top_level do
      namespace :child_one do
        params do
          requires :token, :type => String
          requires :id, :type => String
        end

        mount V1::Controllers::ChildOneController
      end

      namespace :child_two do
        params do
          requires :token, :type => String
          requires :id, :type => String
          requires :name, :type => String
          requires :description, :type => String
        end

        mount V1::Controllers::ChildTwoController
      end

As both child_one and child_two routes require token and id, is it possible to move them up to the top_level namespace? I tried the following but it doesn't seem to work:

    namespace :top_level do
      params do
        requires :token, :type => String
        requires :id, :type => String
      end

      namespace :child_one do
        mount V1::Controllers::ChildOneController
      end

      namespace :child_two do
        params do
          requires :name, :type => String
          requires :description, :type => String
        end

        mount V1::Controllers::ChildTwoController
      end

The params don't carry over mount. I think it should be possible, labelling as a feature request.

Would implementing this not cause some potential breaking changes? Generally I would have thought to use the SharedParams helper approach for these cases.

It would, so we would need to do this carefully. Note that params without a method following it right now is not useful at all, maybe we could be producing a warning in that case to start?
