Intel are looking to get involved in CPython core development specifically to work on performance improvements, so it's important to offer folks in the community good reasons for why we're OK with seeing at least some of that work applied to Python 2, rather than restricting their contributions to Python 3.

I think that's fine, for all the reasons you, Toshio, and others mention. For better or worse, Python 2.7 is our LTS release so I think we can make life easier for the folks stuck on it .

However, I want us to be very careful not to accept performance improvements in Python 2.7 that haven't also been applied to Python 3, unless of course they aren't relevant. Python 3 also has a need for performance improvements, perhaps more so for various reasons, so let's make sure we're pushing that forward too.

In many cases where you have a long lived stable release and active development releases, it's generally the policy that fixes show up in the dev release first. At least, this is the case with Ubuntu and SRUs, and it makes a lot of sense.
