Rule to prevent assigning any value to a variable named undefined

The docs for the no-undefined rule gives this example. I don’t want to use the no-undefined rule, since I use undefined in many places. But it would be useful to have a rule that doesn’t allow the shadowing of undefined to happen, where you can’t assign a value to a variable named undefined in any way. (Like var, let, const, destructuring, function arguments, etc)

function doSomething(data) {
    var undefined = "hi";

    // doesn't do what you think it does
    if (data === undefined) {
        // ...
    }

}

This is pretty specific, so I’d suggest creating a custom rule instead.

It looks like there is consensus that this would be a better fit for a custom rule, so I’m going to close this issue. Thanks anyway for the suggestion – if you do end up implementing a custom rule for this, feel free to link it here.
