Ten years ago, I was an acid reader of the tc39 (EcmaScript standard committee) mailing list and cancelable promises used to be the hot topic for a while.

I unsubscribed at some point because I wasn't working with JavaScript this much, but it's disappointing to see that this work has gone nowhere in the meantime.

I like how Rust futures are canceled by dropping them, even though it's also a footgun (though IMHO this is more of a problem with the select! pattern than with drop-to-cancel proper).
