I don't think that back porting features to 2.7 it's in anyone's radar anymore given that it goes end of life in just over 7 months. Anything that isn't already there is likely not going to benefit many people
You'd be surprised I think. In my job, EOL noticed are all it takes, often, to push people onto the next version, even reluctantly. I imagine many situations where Python 2 is still used are not developer driven but, rather, business value propositions. Many of my clients wouldn't understand a discussion about upgrading because of Unicode strings, but if I were to mention to my clients that Python 2 is no longer receiving bugfixes and officially has reached EOL status you can bet they would all throw money at it.
