It does have those:

  *** Welcome to IELM ***  Type (describe-mode) or press C-h m for help.
  ELISP> +
  *** Eval error ***  Symbol’s value as variable is void: +
  ELISP> #'+
  +

But I get it, you mean namespaces like Common Lisp packages so people don't need to call stuff `org-babel-load-languages', but they can just call it `load-languages' and put it in the `org-babel' package.

Yes I meant packages :)
