I don't think anyone™ goes out of their way to explicitly break things for old Python versions.

It's usually more like "oh cool I can make this code faster/more readable if I use this feature. I don't have to care about the old version anymore so I will do that."

If you really to super duper need a backport, you're in luck: python is an interpreted language whose source is in plaintext, on your local machine.
