Sure, but “until 3.2” covers a long enough time to take us from now to “deprecation of Python 2”. Given that the Requests team is 4 people, unlike python-dev’s much larger number, I suspect we’d have at least as much pain proportionally as Python did. I’m not wild about signing up for that.

Ok, let’s address those together.
There are security reasons to do the backport, but they are “it helps us build a pathway to PEP 543”. Right now there are a lot of people interested in seeing PEP 543 happen, but vastly fewer in a position to do the work. I am, but only if I can actually use it for the things that are in my job. If I can’t, then PEP 543 becomes an “evenings and weekends” activity for me *at best*, and something I have to drop entirely at worst.
Adopting PEP 543 *would* be a security benefit, so while this PEP itself is not directly in and of itself a security benefit, it builds a pathway to something that is.
As to the plans to move Requests to a more event loop-y model, I think that it does stand in the way of this, but only insomuch as, again, we want our event loopy model to be as bug-free as possible. But I can concede that rewording on that point would be valuable.
*However*, it’s my understanding that even if I did that rewording, you’d still be against it. Is that correct?
