If I'm understanding you correctly, I don't believe that's the intended use for this technology. This is about streaming an application over the Internet, from a remote server, not from a localhost server. I can't think of any advantage to building a locally hosted Qt app that way. If you want to run a Quick/QML app locally, you just run it — there would be no gain and numerous penalties in running it through a web browser. (It also doesn't seem useful to compare it to Electron-based apps. The Qt comparison to an Electron app would be a Qt/QML app that uses Qt's WebEngineView, a control that embeds the Chromium browser.)
