This probably won't have much impact on performance because item renderers shouldn't invalidate if nothing has actually changed. However, there is a perception that update is being called too frequently, so best to avoid it, if possible.
However, I need to remember to still handle updateAt and updateAll forced updates, even when no properties were changed.
