I think you could have web rich documents with basic interactivity and as an option web application that are "native app like" , with tons of APIs for camera/microphone , bluetooth, canvas, 3d , complex sound APIs. We have to admit that rich web application can be very usefull, even during Java or Flash days we known that sometimes you need an animation or a simulation on a page to better present some content. Though it makes you think if we had an 100% open source Flash, then you could have used it for complex SPA like Figma while keeping all the bloat into an optional plugin , if the plugin was optional developers would not be tempted to use it unless is needed and it it was needed they would have use something like Flex (a Flash GUI tookit) and not reinvent the wheel constantly.
