Yes, the existing ":results silent" option still echos the results to
the minibuffer. It was originally added in the case where one does not
want to change the Org-mode buffer (but would still like to see code
block output).
The attached patch adds a "really-silent" results header argument. To
see the impact compare the running time of the following two code
blocks.
#+begin_src sh :results really-silent
seq 100000000
#+end_src
#+begin_src sh :results silent
seq 100000000
#+end_src
Before such a patch is applied it would need corresponding
documentation, and the "really-silent" moniker may need to be
reconsidered in favor of something more informative (the main purpose of
this header argument is not silence but is rather avoiding all post
processing), and ideally shorter as well. These new header arguments
are of no value if they are not easily discover-able and easily
remember-able to help others avoid the same issue that launched this
thread.

Subject: [PATCH] "really-silent" header avoids result post-process
This patch introduces a new header argument which hide all code block
results from Emacs so that they are not processed into Emacs-lisp
objects; a process which may take a great deal of time for large
objects.
* lisp/ob.el (org-babel-common-header-args-w-values): Adding the new
"really-silent" header argument.
(org-babel-execute-src-block): Don't do *any* result processing if the
"really-silent" header argument has been specified.
(org-babel-sha1-hash): Remove the really-silent header argument from
header arg lists when calculating cache sums.
(org-babel-insert-result): Flesh out some documentation.
