I don't want to split grammatical hairs, let's look at the source.

(The expiration selection code in sgnus v0.18 is unchanged from Gnus
5.0.12.)

As I read the code, all article expiration is done through the
function gnus-request-expire-articles, which selects the appropriate
backend expiration function, *and* calls gnus-group-real-name on the
newsgroup parameter.  Therefore, if your expiry-wait function is
getting the newsgroup with the method left in, that's a bug.


[ These are cut & pasted from 5.0.12]

[ This function gets group with the method still attached, as returned
by gnus-group-group-name. ]

(defun gnus-request-expire-articles (articles group &optional force)
  (let ((method (gnus-find-method-for-group group)))
    (funcall (gnus-get-function method 'request-expire-articles) 
             articles (gnus-group-real-name group) (nth 1 method)
             force)))


(defun gnus-group-real-name (group)
  "Find the real name of a foreign newsgroup."
  (if (string-match ":[^:]+$" group)
      (substring group (1+ (match-beginning 0)))
    group))

Are you sure your wait function really works, or is everything
expiring after the (same) default amount of time?


I match explicitly on group name sans method in my
expiry-wait-function, and I've verified that expiration does occur
based on the value returned by it.
