Why is the "setter defined without getter" JSHint error?

Question

Jsfiddle link

var obj = {
  set bla(k) {
    console.log(k);
  }
};

JSHint refers to this as "setter defined without getter". I am sure there is a way to disable this, but why is this a mistake at all? All that I saw, the JSHint flag had a reasonable explanation. I can’t think of why this is bad.
