This should be defined on the field it modifies, not added to another Class attribute.

The "return" types should just be a meta field inside the INPUT_TYPES definition which really should be "NODE_DEFINITION".

I would be 100% behind and supportive of a movement to fix the core design problem so that any future "metadata you want to manipulate in the UX layer" is a no brainer with a simple adding of any field you want to the widget define, RETURN fields included.

    @classmethod
    def NODE_DEFINE(cls) -> dict:
        return {
            "required": {},
            "optional": {},
            "return": {},
            "hidden": {}
        }

I am not sure how to get there from here given the current movement of core changes, but I really do not feel adding this gives any benefit in the long run versus just re-wiring the core to remove any future question about custom metadata in custom nodes.
