I think that this discussion goes in same circle than about a year ago.
At least there is not majority wanting to move code from categories/* to combinat/*. Hence I guess it will not be done. So, what to do with http://trac.sagemath.org/ticket/18534 ? Somebody could give it a positive review and either let milestone be 6.8 or change it to wontfix.
(Or say that something else should be done to documentation.) -- Jori Mäntysalo
