All session backends honor this setting, except for `sessions.backends.cache.SessionStore`, which still uses pickle as serialization format (not directly, but via cache backend).
It should be documented that cache store ignores this setting or SessionStore should be modified to support it."	Cleanup/optimization	assigned	contrib.sessions	1.7	Normal		pickle json sessions		Accepted	1	1	0	0	0	0
