And it’s not just Rust. I think there’s a handful of newer languages people would love to use for writing native desktop apps, but the frameworks and tooling aren’t there.

For me that’s Swift. I don’t even need a UI framework that tries to be a silver bullet write-once-run-everywhere or one that strives to fit into the paradigm-du-jour; just give me something that’s serviceable with a decent loudout of widgets (many newer frameworks weirdly skip critical pillars like tableviews/datagrids) that I use to write per-platform UIs around a common Swift core.
