Comment (by Claude Paroz):

With my usual conservative hat on, I'd plead to not drop Python 3.7
support too soon. It's still widely used in stable systems (namely Debian)
and asking contributors running those systems to install a Python version
"by hand" to contribute to Django master branch is not friendly at all.

I understand your concerns, but there's not consensus to change the
policy on the mailing list. Also, if not in Django 4.0 then we will need
to support Python 3.7 to Django 4.2 LTS (end of life April 2026), so 2
more years, and almost 3 years after the last Python 3.7 release.

Comment (by Claude Paroz):

I know my practice (using latest released Django on as-much-stable-as-
possible systems) is not on the majority side, so you'll never find a
consensus to change the policy.
