    33While `CombinedExpression._resolve_output_field` resolving logic deals with subclassing properly `BaseExpression._resolve_output_field` [https://github.com/django/django/blob/2848e5d0ce5cf3c31fe87525536093b21d570f69/django/db/models/expressions.py#L327-L329 isn't smart enough] to resolve a mix of `IntegerField` subclasses to the largest denominator.
