Missing standard downstream promise cancellation is arguably one of the bigger problems in the whole javascript ecosystem. In C# almost every async function has a CancellationToken parameter, same in Go with Context. Even after years of writing fullstack javascript this is my first time seeing AbortSignals, probably because nobody uses them. Some libraries, like Axios, handroll their own cancellation mechanisms, but that does not really cut it.
