I reviewed these methods in wikipedia.py and a part of them uses API, while lot of them analyzes HTML source.

Russell is talking about the rewrite branch, at http://svn.wikimedia.org/viewvc/pywikipedia/branches/rewrite/pywikibot/ . 

Yes, I realized that but he told these were taken from trunk. At the moment, I am only interested in trunk and try to guess which special pages are subject to write an API interface and which are already written.
