My vote is no - it doesn't make sense. Let the user pick `:results list' 
or `:results pp' after it returns a string.

BTW, the string produced when a list cannot be rendered as a table ought 
to be removable.

The patch makes such strings removable. i.e.

#+BEGIN_SRC emacs-lisp
org-babel-load-languages
#+END_SRC

will have the ": " prefix or #+begin/end_example delimiters to allow later 
removal like this:

#+RESULTS:
: ((R . t) (latex . t) ... (sql) ...
