The availability of smart operators will be configurable on the operator
by operator basis, I just don't yet have a clear idea of how to do
that. So it would premature to implement something ad-hoc right now. 

Also comma would be the last operator I would like to disable on
comments; cannot come with one single example in R where space would
not be recommended after comma.

For time being, if you really want it, you can slightly redefine the
function yourself:

(defun ess-smart-comma ()
  "If comma is invoched at the process marker of an ESS inferior
buffer, request and execute a command from `ess-handy-commands'
  (let ((proc (get-buffer-process (current-buffer))))
    (if (and proc
	     (eq (point) (marker-position (process-mark proc))))
	 (cdr (assoc (ess-completing-read "Execute" (sort (mapcar 'car ess-handy-commands) 'string-lessp) nil t)
      (if (and ess-smart-operators
	       (not (ess-inside-string-or-comment-p (point)))) ;; <-  added this
	    (insert ", "))
	(insert ","))
