This will taken care of by #15246.

In the meantime, since you are only interested in the presence of the property and don't need a deep copy of it, you can convert it to boolean when using it inside ngClass (see below). This will also improve the performance.

// Replace that:
<div ng-class="{foo: $ctrl.someLargeObject}"></div>

// With this:
<div ng-class="{foo: !!$ctrl.someLargeObject}"></div>
