We are relying on a Django object to implement the feed so if anything,
this should be improved at this level:
https://docs.djangoproject.com/en/1.11/ref/contrib/syndication/
I would suggest to file your suggestion to the Django developers.
Unless Django expects us to setup a ConditionGETMiddleware to replace
the answer by a NotModified answer:
https://docs.djangoproject.com/en/1.11/ref/middleware/#module-django.middleware.http
We could enable this but I wonder if it would have other unexpected
side-effects in other parts of the code.
Cheers,
