   Essentially, what's requested is some stable place to post (and leave 
posted) a
   bit of general info - info that is not specific to any buffer or window or
   frame...

Perhaps ‘message’ could be extended to recognize a distinguished text property
and arrange for that text to be placed in a *State of the Emacs* buffer
(perhaps indexed/formatted/prettified in some way by that property's value),
in addition to being added to *Messages*.  Something like:

  (defun message/stateful (category fmt &rest args)
    (message "%s" (propertize (apply 'format fmt args)
                              'message/stateful
                              category)))
  
  (defun note-stateful (category text)
    (with-current-buffer "*State of the Emacs*"
      (goto-char (GOOD-PLACE-FOR category text))
      (apply 'delete-region (REGION-OF-OLD category))
      (insert (APPROPRIATELY-DECORATED category text))))

where ‘note-stateful’ is called by ‘Fmessage’.
