The language documentation on Worg, such as
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-R.html, is
meant to be documentation, rather than tutorial. It is structured this
way so the manual doesn't need to be updated every time support for a
new language is added, or changes are made to a language-specific file.
The template for this documentation includes a slot for default header
arguments and also one for language-specific header arguments, because
these are often changed by the language-specific modules.
I think the hope and expectation is that the user community take over
the tasks of creating and tending the language-specific code. If
:results graphics makes good sense for Python, then users should feel
free to add it to ob-python.el. With the examples you point out, it
shouldn't be too difficult.
hth,
Tom
