@hukl @moonglum @janl this might not be your use case: but especially when teaching people to code for the web (dojos or rails girls), the most rewarding experience was to a) deploy your app to your domain and b) hit that "add to home screen" button. This was the "wait wait wait, so… …I just built an app?" coin-drop moment & they could take their app home & show it around.
PWAs might be a niche, but they lowered the bar so much for what it means to be an "app". I'd be sad to them go.
