Wouldn't call 28% "largely ignored", rather "still lagging behind". Thing is, 3.6 looks like the real deal breaker here, what Python 3.0 should've been. With asyncio, compact dicts and scandir I've gotten to the point where I can almost justify to my employer why, if everything is still working, we should move to Python 3.6 ("all will be faster" -- I know I'm kind oversimplifying here, but my boss pretty much doesn't understand software and just wants results/money).
There's also the sentiment of "I don't know if [insert module here] will be supported", which has become mostly baseless fear, but people still think Py3 support is lacking (when it's not![0]).

Edit: when I posted this comment, the link was titled "Python 3 largely ignored" (not the article per se, but the submitted link had been titled that way). It has been changed, but this was a bit of important context for my comment.
