Why is Performance an EventTarget?

Why is Performance an EventTarget?

interface Performance : EventTarget {
    ...
};

I didn't see any events that would be dispatched on Performance, so registering listeners would seem unnecessary. Is this in preparation for the future or are events dispatched in a related spec?

https://w3c.github.io/resource-timing/#dom-performance-onresourcetimingbufferfull is one example.. As such, I believe we need the EventTarget?

Ahh, that makes total sense. Closing, thanks!
