Whatever you write in python,you must commit to maintaining it yearly. If you write software and people buy it,you have to update it once in a while.

There are many use cases where this won't fly and it's fine to use something more standardized and stabilized. They should have done this a long time ago to avoid the 2.x -> 3.x headache.

Undesirable for those of us that sorta depend on stackoverflow answers to get a lot of things done but I am sure there's a bigger picture the python devs are seeing.
