Trouble with net/cookies

I seem to be unable to use the net/cookies package together with the web-server/servlet.
With

(require web-server/servlet
         web-server/servlet-env)

(require net/cookies)

I am told

module: identifier already required
  also provided by: web-server/servlet in: make-cookie

But if I leave out the (require net/cookies) the names documented in Cookies: HTTP State Management are not available.

(require web-server/servlet
         web-server/servlet-env)

;(require net/cookies)

cookie-name?

Have the names changed? Is there some new way to handle cookies now?

If you don’t want make-cookie from web-server/servlet, use this:

(require (except-in web-server/servlet make-cookie)
         web-server/servlet-env
         net/cookies)

(require web-server/http/cookie) seems to do the job.
