A faster workaround than my first, but which doesn't rely on duplicate
suppression:

    (defun spw/gnus-summary-read-group (group &rest _ignore)
      (when (string-prefix-p "nnselect:" group)
        (with-current-buffer gnus-group-buffer
          (save-excursion
            (gnus-group-goto-group group)
            (gnus-group-get-new-news-this-group 1)))))
    (advice-add 'gnus-summary-read-group :before #'spw/gnus-summary-read-group)
