As [https://groups.google.com/d/topic/django-
developers/zdULZcmAWNw/discussion discussed on django-developers], ticket
#18773 added logging of undefined template variables in Django 1.9
[dc5b01ad05e50ccde688c73c2ed3334a956076b0], however, I've seen several
reports of users finding this logging more confusing than helpful. For
example, [https://groups.google.com/forum/#!topic/django-
users/6Ve9dcv23sI/discussion admin templates log errors about missing
is_popup variables] which is how the template are designed (is_popup is
only in the contexts of pop ups) and the `TECHNICAL_404_TEMPLATE` (now
`django/views/templates/technical_404.html`) also logs errors (#26886)
without any obvious solution about how to prevent that. Also #28516 shows
the many warnings logged for an admin changelist page.
