I'm not sure of the meaning of "buried" here. What do you mean? We propose to revert 5 changes:
* Removed tostring/fromstring methods in array.array and base64 modules * Removed collections aliases to ABC classes * Removed fractions.gcd() function (which is similar to math.gcd()) * Remove "U" mode of open(): having to use io.open() just for Python 2 makes the code uglier * Removed old plistlib API: 2.7 doesn't have the new API
Basically it isn't easy to discuss the things you want to revert here, especially since you grouped them all together. Are you planning to start separate conversations on the (I think) 5 things you want to change?
It's not only about specific changes, but more a discussion about a general policy to decide if a deprecated feature should stay until 3.10, or if it's ok to remove it in 3.9.
Given that we’ve changed the release cadence to one major release per year, it doesn’t seem that much of a burden to revert and carry these changes forward into Python 3.10. And if it helps with the migration off of Python 2.7, then +1 from me. -Barry
