I see.

But it will disable the existing features concerning the parameters
of which the names don't begin with "gnus-" and  "mm-".  The best
way seems to be to add "gnus-" or  "mm-" to all the parameters.
However, it will take time for coding and verifying.  Maybe, it
should do after the Emacs 23.1 release.

Oops, I use `gnus-group-set-timestamp' as `gnus-select-group-hook'.
I don't recall why I added it to the hook, though.
