Hello Webkit-dev, I would like to ask for Webkit's official position on WritableStream controller's AbortSignal API < https://streams.spec.whatwg.org/#writablestreamdefaultcontroller-signal and https://streams.spec.whatwg.org/#writablestreamdefaultcontroller-abortreason> specification. This feature permits an underlying sink to rapidly abort an ongoing write or close when requested by the writer. An underlying sink which doesn't observe the controller.signal will continue to have the existing behavior. In addition to being exposed to streams authored in JavaScript, this facility will also be used by platform-provided streams such as WebTransport. See spec change pull request: https://github.com/whatwg/streams/pull/1132 TAG Review: https://github.com/w3ctag/design-reviews/issues/672 Chrome Platform Status Entry: https://chromestatus.com/feature/5698931422920704 Thanks, Nidhi Jaju
