When native support for tuple lookups is missing in a DB backend, it can
be emulated with an EXISTS clause. This is controlled by the backend
feature flag "supports_tuple_lookups".
The mishandling of subquery right-hand side in `TupleIn` (added to
support `CompositePrimaryKey` in Refs #373) was likely missed because
the only core backend we test with the feature flag disabled
(Oracle < 23.4) supports it natively.

Value(None, JSONField()) when used in When.condition incorrectly resolved with
for_save=True, resulting in the value being serialized as SQL NULL instead of
JSON null.

When matching which entry in the `Accept` header should be used for
a given media type, the specificity matters. However once those are
resolved, only the quality matters when selecting preference.
