Michal Mocny If we had something like https://github.com/whatwg/dom/issues/1038, with an API that uses promises for one-time events, such as

const img = new Image();
img.src = imgURL;
await img.eventPromise("load");
//

do you think it would be still as important to implicitly propagate the context through load/error events? I'd assume that most web developers would prefer the promise-based API for one-off events where the "after" is a logical consequence of the "trigger"
