On second thought, I guess the existing policy already does this. Maybe we should make it more than 2 versions for deprecations? I've written libraries where I support 4 or 5 released versions. Although maybe I should just trim that back.
If I understood correctly, the problem is more for how long is the new way available?
I think the main problem is how many user code will be broken and the merit of the deletion. For example, PEP 623 will remove some legacy C APIs in Python 3.12. https://www.python.org/dev/peps/pep-0623/ There are a few modules the PEP will break. But the PEP has significant merit (reduce memory usage of all string objects). So I want to remove them with the minimum deprecation period and I am helping people to use new APIs. (*) * e.g. https://github.com/jamesturk/cjellyfish/pull/12 So I don't want to increase the minimum required deprecation period. But I agree that a longer deprecation period is good when keeping deprecation stuff has nearly zero cost. Regards, -- Inada Naoki <songofacandy@gmail.com>
