> The web, and the browser by extension, is a multimedia platform.

Says who exactly though? The big companies and web devs who think your browser needs raw access to HIDs? Why exactly does a web browser need this level of access when a native application is far superior (and doesn't need to deal with the limitations of a web browser)? All this does is require that browsers be more and more complicated and be more and more invasive so that we can pretend that the web browser is our operating system. That in turn makes it harder and harder for web browsers to even be implemented in the first place.
