Up until 2016-08-23, Service Workers were marked in MDN as experimental [1], despite the concentrated push by various parties to get people to stop using stuff like AppCache and use Service Workers instead. That being said, at least Dialog is part of both the WHATWG HTML5 "Living Standard" (a fancy name for snapshot), and the W3C HTML 5.1 Recommendation, making it approved and finalized by both the practical body of rapidly-evolving browser makers and the political body that historically set web standards. In contrast, Service Workers are still a draft, despite having been pushed for years, and its predecessor technologies having largely been deprecated. In other words, this is quite normal in the world of the Web Platform today, for better and for worse.
