I cannot think of a worse programming paradigm. The problem it solves is there
is a lot of HTML/CSS/JS "talent" out there. That's it. I reject DOM and CSS as
the best way to do structure and presentation, and JS is a terrible language.

I don't see how having a web browser render everything isn't the most heavy
weight approach imaginable.

Widgets are nice, I love them still, but QML is hardware accelerated to the
core with proper threading. It is unfortunate that QML's UI elements are so
terrible at actually working and being rendered consistently, as widgets were.
If we could do widgets in QML, that would be the way to go. The layouts were so
Having done X-Platform mobile in Android Native and Qt 2013-2017, it's
sometimes just easier to just throw it all away and roll your own. The
platforms have bog differences, there are no physical back buttons on iPhones,
so you need UI space to compensate. On the good side, this is easy, on the bad
side, it's not as simple as widgets were - where everyone had the same input
hardware. On the good side, it is popular to have your own app UI, and there is
no real platform standard UI layout like widgets had. I so wish I could throw
something together like in the old days. But UI designers would not have jobs,
even though the UIs are far less consistent than old. On the flip side, they
look a hell of a lot better.
Anyway, you can lament it, but that ship has sailed.
If you really want to know what I'm thinking, it would be to ditch JS entirely
and use ChaiScript in QML.
