I believe there is a feeling that org-babel is already so complicated that adding features should be avoided.
There are workable approaches under the current setup.

For one, you can define lang specific header-args, so just define :eval no for the lang's that you want to use, but that do not have org-babel-execute:<lang> defined:
#+property: header-args:nada :eval no
#+property: header-args :exports both :eval yes
The code here will be rendered, but the block will not execute:
#+begin_src nada
"haha"
#+end_src
---
Another is to use a custom :eval arg like this:
#+property: header-args :eval (my-eval-p) :exports both
#+begin_src not_defined
"haha"
#+end_src
Where `my-eval-p' is defined as:
#+begin_src emacs-lisp
(defun my-eval-p ()
(let ((lang (car (org-babel-get-src-block-info 'light))))
(if (fboundp (intern (concat "org-babel-execute:" lang)))
"yes"
"no")))
#+end_src
Obviously, you can elaborate `my-eval-p' to satisfy individual needs.
Best,
Chuck
