Expression to negate has()?

[Madd0g]

Hey, I'm trying to filter objects that have one property, but don't have another. Is there a way to do that? Given this structure:

{
    people: [
        {
            name: "Betty",
            friend: { name: "Robert" }
        },
        {
            name: "Victoria",
            friend: { 
                name: "Chris", id: 1,
                people: [
                    {
                        friend: {
                            name: "Jon"     
                        }
                    }
                ]
            }
        },
    ]
}

I use this selector: object:has(.friend > .name) but I also want to include a condition - to get those friends that don't have an id, something like: object:has(.friend > .name):hasnot(.friend > .id) (to get objects that contain Robert and Jon, but not Chris)

Is this possible?

The CSS 3 :not selector has widespread support, it would be good to see support for it here.

Just noticed this original issue is nearly two years old, hmmm....
