Thanks for answering. You are correct that they are under development but they're moving pretty slowly and I got the feeling contribution would be really appreciated. For example, `fetch` in service workers - caching and request intercepting could really improve the "default" iPhone experience in PWAs. I realize that getting this request is annoying (Build a feature in another browser) but I really think it could significantly push the web as a whole. It would also be great to see the Chrome team fix some of the more annoying bugs in the existing APIs (WebRTC has some really annoying ones).
