18807	Inconsistency in the default views	Aymeric Augustin	nobody	"`django.views.defaults.permission_denied` will respond ``<h1>403 Forbidden</h1>`` if no ``403.html`` template is found. This behavior was introduced to provide [https://code.djangoproject.com/ticket/5515#comment:16 backwards compatibility]. Generally speaking, it is a reasonable fallback.

I believe that `page_not_found` and `server_error` could benefit from a similar fallback.

That would prevent 404s from turning into 500s when there's no 404.html template. I know we want to encourage custom error pages, but in case a developer skips them, a bare ``<h1>404 Not Found</h1>`` is less damaging than a 500 with a backtrace or no content at all."
