[plt-scheme] provide/contract

With the new custom require and provide forms, is there a plan in the  
works to merge provide and provide/contract? It'd be quite useful to  
be able to do this:

(define-struct person (name age))

(define (create-person name)
   (make-person name 0))

(provide (except-out (contract-out struct person ([name string?] [age  
          (rename-out ((contract-out create-person (-> string? person?))

I currently do this sort of thing with two modules: a private module  
defines and adds contracts to the structure type, while a public  
module does the renaming and hiding of the default constructor.
