Short name for ko.utils.unwrapObservable

I always found the name for this function way too long and after having it written so many times in my custom binding handlers and in various other places I added the following piece code to my own sources:

    if (typeof ko.unwrap === 'undefined') {
        ko.unwrap = ko.utils.unwrapObservable;
    }

How about adding the function `ko.unwrap` to knockout?
