        Well, just to be clear, C-h p C-s games RET RET results in the
        following list on Emacs 24.3.1.

        To me, the failure of the recent development version to show the
        above seems like a regression, regardless of the particulars.

        If the change made to package.el was indeed intended, then my
        guess is that it should’ve been complemented with the changes to
        all of the packages above to make them fit the newly imposed
        criteria for inclusion.
