It is a New Feature and therefore ineligible for adding to 3.5 or 3.4.

I think this is a good idea So do I. , but this is a CPython-the-implementation feature, rather than a Python-the-language feature, so it isn't clear what rules apply to adding it. Certainly add it to 3.7. I think the decision whether to add it to 3.6 and the stable releases should be up to the respective release managers. As you say, it's not a language feature, but it's still a new feature and as such it does fall within a gray area. I'd personally have no problem with adding it to 3.6 and possibly earlier stable releases, but I'm not an RM of any active releases any more. I'd say, open a bug, post the patch against the versions you want to see it applied to, go through the review process, and let the RMs decide if its worth the risk. Cheers, -Barry
