Yes.

This happens already, but the JS would also have to create the
corresponding CSS code (that's what I hardcoded in the patch).

However you'd still need a mapping from src block identifier to
pleasantly readable text, e.g. js -> "Javascript", sql -> "SQL",
emacs-lisp -> "Emacs Lisp", ps -> "PostScript" etc.  When you have all
those it's not that much different from static CSS anymore...

There's no perfect solution, unfortunately, but src blocks have a lot
of limits for each language:
- is there an Emacs mode for editing?
- is there org-babel code for executing?
- is the language supported by the LaTeX listings package?
- or by the pygments library (for the LaTeX minted package)?


Anyway, my patch is basically for those who don't roll their own CSS to
have things mostly working out of the box. 


Best regards
Robert
