Release Note Request (optional, but appreciated)
[Why is this notable]: New web platform feature
[Affects Firefox for Android]: Not specifically; it's a Gecko change.
[Suggested wording]: Firefox support for an emerging web platform feature, ReadableStream.
[Links (documentation, blog post, etc)]: Jake Archibald wrote a blog post about potential use cases here: https://jakearchibald.com/2016/streams-ftw/. Some popular websites use this feature to create better experiences for users of browsers that support it.

Sorry, I couldn't come up with something great for suggested wording.

Per offline discussion, we want to add this to the developer notes but not the user-facing relnotes.

Note to MDN team:

I have added a note to the Fx65 rel notes covering this:
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/65#APIs

In terms of the documentation, I wrote fairly complete streams documentation a while ago. We'll need to update compat data, but more than that we'll need to check it thoroughly to see what's changed, what needs to be updated, etc.

OK, documented! I've removed the experimental banners and updated compat data on appropriate places now this functionality is in two engines by default:

https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream
https://developer.mozilla.org/en-US/docs/Web/API/ReadableStreamDefaultReader
https://developer.mozilla.org/en-US/docs/Web/API/ReadableStreamDefaultController

I've also looked to updated compat data in these places:

https://developer.mozilla.org/en-US/docs/Web/API/Request/Request
https://developer.mozilla.org/en-US/docs/Web/API/Body
https://developer.mozilla.org/en-US/docs/Web/API/Streams_API/Using_readable_streams

The PR for updating the compat data is here:
https://github.com/mdn/browser-compat-data/pull/3307

Let me know if this looks OK. Thanks!
