Thanks for this clarification.

But in that case let me return to and refine my proposal:  Why not have
"drawer" as the default unless "raw" is given?  

One could argue, that the extent of the results is implicitly given
when the results are not "raw", but being explicit here would allow for
some additional features (such as different background for results -- is
anyone doing this? I'd be interested).

One could also argue, that the users are free to put their results in
drawers if they wish.  But on the other hand what would be lost by
defaulting to drawers?

Having said all that, I want to add, that I do not particularly like the
visual appearance of drawers for results blocks;  I think they
- add one more line than necessary and they
- differ too much from the appearance of source blocks

This is the state in org           This is what I'd prefer...  
--8<------start-------->8---       --8<------start-------->8---
#+PROPERTY: results drawer         #+PROPERTY: results drawer  
                                                               
* Test                             * Test                      
#+name: dtrn                       #+name: dtrn                
#+begin_src R :exports both        #+begin_src R :exports both 
  "hello"                            "hello"                   
#+end_src                          #+end_src                   
                                                               
#+results: dtrn                                                
:RESULTS:                          #+begin_results dtrn        
hello                              hello                       
:END:                              #+end_results               
--8<-------end--------->8---       --8<-------end--------->8---


But do not take this too seriously.  I am more than happy to live with
the standard appearance of drawers here.
