Meanwhile, the Python 3 Wall of Superpowers is looking really good. 166/200 major watched projects are Python 3-compatible. https://python3wos.appspot.com
Funny. I wrote a really small utility program with BeautifulSoup in Python 3. Coworker wanted to host it on AppEngine, but it supported only Python 2 for some reason. So he ported it. I am not sure what they support now, but it seems that the WoS application itself has to be in Python 2. :-)
The google-api-python-client is what bothers me the most. They work on convincing top CS departments to teach CS101 in Python, and as soon as the majority switch it feels like they've kind of abandoned the language. From what I can gather from Github, it looks like there is all of one person working on this part time.
I don't know where you got this, but it was never planned to have been dead two years ago. 2.7.0 happened in July 2010, and regular bug and security fixing would still have been happening up until around this time regardless of anything else (fwiw, 2.6 went from 2008-2013). Instead, we decided earlier this year to extend that support until 2020.
