Transferable streams permit streams to be transferred to a worker or other realm using postMessage(), where they can be used just like the original stream.
Example:
const rs = new ReadableStream();
window.postMessage(rs, '*', [rs]);
See the explainer https://github.com/whatwg/streams/blob/master/transferable-streams-explainer.md for more motivation.
See the spec change at https://github.com/whatwg/streams/pull/1053 and the web platform tests at https://github.com/web-platform-tests/wpt/pull/24546.

I accidentally found out that it only happens if you use the following header:
Cross-Origin-Embedder-Policy `credentialless` instead of `require-corp`.
Other engines are tolerant of this difference.
Is it on purpose?

+1. It sucks that I can't use `ReadableStream` between workers, makes my abstraction much worse.
