Since Django 5.2 Django emits this warning.

>WARNING: This is a development server. Do not use it in a production
setting. Use a production WSGI or ASGI server instead.
For more information on production servers see:
https://docs.djangoproject.com/en/5.2/howto/deployment/

I _know_ this and act like it. To avoid warning fatigue, I keep the number
of displayed warnings as close to 0 as possible. Doing so is annoying for
the current warning (it can be done via the env, but not using a setting).

I would like to have a first-class tool to get this thing to shut up :-)

Discussed [https://blog.pecar.me/disable-runserver-warning-in-django-5-2
here] and [https://adamj.eu/tech/2025/06/27/django-hide-development-
server-warning/ here] (with similar reasonings)
