in_place_edit_for API page

Today I googled to see where in_place_edit_for wandered off to and I saw that the first result was this page: http://api.rubyonrails.org/classes/ActionController/Macros/InPlaceEditing/ClassMethods.html

Since this doesn’t exist in Rails anymore, can we get it removed from the site? Otherwise, people may continue to think that this is still in Rails.
