> I struggle to see where you would prefer Qt for frontend code if you don't need a native app.

Specially on mobile. their decision to go with QML for mobile OS support, requiring devs to replicate native widgets, means it is a bigger effort to create multiple QML frontends, than it is to follow a MVVM architecture with as much code as possible in C++, while using native support directly, even if in different languages.

Also for those targeting mobile OSes, Xamarin has a much support for the respective OS APIs than Qt, that usually requires the extra effort of manually wrapping many of them.

As someone that prefers working on native apps to web ones, I kind don't understand their current roadmap, it appears that they are trying to spread between C++ and JavaScript devs in an attempt not to lose mind share.
