QML is an entirely separate widget toolkit that really isn't a great fit for desktop programs - it's not much different from using a web-based toolkit.
QML doesn't have a way to define interfaces with JSX and doesn't integrate with the wider JS tooling. From my very limited experience, it still feels too close to the C++ world.

By all means, I'd be happy to be proven wrong. Last effort I saw on this direction was node-gui + React. I believe that project isn't being maintained. Being able to use something like Vite to build desktop programs would be a blessing.
