This is wishful thinking.

There's a cost to maintain, and that's why PSF is moving to 3. I'm sure if Google and/or Dropbox would pay, PSF might continue maintenance[1].

Anyway the issue here is that you won't get any new features in python 2.7, and that already happened last year, currently python 2 only gets security fixes.

> have you tried using gevent versus asyncio ? gevent is running in production at several of the largest API services in the world. Asyncio is not yet deployed at this scale.

Both of them are available on python 3. On python 2 you can't chose. AsyncIO strength is that it is integrated into the language. Especially in 3.5 you have a new syntax to use it, no need to install new libraries, no need to compile anything. No monkey patching. Also AsyncIO is more generalized and could be adapted to other tasks, not necessarily for asynchronous calls.

[1] In fact surely Red Hat will continue to maintain it until 2027 since they decided to ship it with Red Hat 7, but question is whether they will share it with general users, or will they only provide it to paying customers.
