>i.e. dissuaded from using native, but rather bespoke, UI frameworks. Based on my experience, I would be quite reluctant to rely on any non-native cross-platform desktop UI framework that is not web-based. These tend to be either less performant, look outdated or are bug-ridden.
What about Qt? It is the gold standard for cross-platform desktop UI frameworks. It is (1) performant (C++-based), (2) does not look outdated, and (3) not bug-ridden.
On Linux, Qt apps feel a bit off in GNOME, though you can never satisfy everyone as its the wild west.
I think Qt also suffers from not really being anyone's favourite.
On the one hand, you have web developers who tend to not really appreciate the nuance of the desktop as a platform. They're not going to advocate for Qt, it's not CSS/HTML/JS.
On the other hand, you have native Mac developers who love Apple's toolkits (AppKit, maybe SwiftUI). They're not going to advocate for Qt either.
Lastly, you have native Windows developers who have been burned so many times they don't advocate for anything in life anymore.
