[webkit-dev] Request for position on Element Timing

Hi, I'd like to request WebKit's position on the Element Timing API, which lets web developers annotate images or text whose performance they care about. They can then obtain rendering timestamps from the PerformanceObserver. For cross-origin images the detailed information is gated on Timing-Allow-Origin. The proposed specification is at https://wicg.github.io/element-timing/ and is currently shipped in Chromium. Thanks!
