Hi, I proposed https://bugs.python.org/issue39352 to remove the formatter module. It's deprecated since Python 3.4. The main reason why it's still around is the PEP 4 rule: "In order to facilitate writing code that works in both Python 2 & 3 simultaneously, any module that exists in both Python 3.5 and Python 2.7 will not be removed from the standard library until Python 2.7 is no longer supported as specified by PEP 373." https://www.python.org/dev/peps/pep-0004/#for-modules-existing-in-both-pytho... Python 2.7 is not longer supported. So can we now remove the formatter module? The module has no test, I failed to find any user in a dummy GitHub code search and I didn't know that this module even existed. We can still revert the module before 3.9.0 final release if someone shows up and asks to keep it for one more cycle. My intent here is to reduce the size of the Python standard library to reduce the maintenance burden. Python became quite large and it's more and more expensive to maintain it. Wait... I'm not asking to remove all modules of the standard library :-) The decision must be taken on a case by case basis, for each module. Here I'm only taking about the formatter module.
