I wouldn't, because I do not think we should put up barriers in our application between OSs (Nor have to maintain separate UI code bases for each OS you think might use it). So I use cross-platform kits. There are compromises, but I don't care about the looks native qualification compared to works anywhere. Yes, the software looks like an EGUI app (etc. Substitute Qt), instead of Looks native, but I appreciate how I'm not setting up barriers between OSs or making extra work.

So instead you are creating a bad UI for all of your users. That’s very Java application (or perhaps Electron these days) of you, but seems like a poor trade-off to me.

These days, with LLM assisted development, with relatively simple GUIs, I would go towards platform native GUIs per platform. And then all the shared business logic goes in a shared "core", with the GUIs only serving as "dumb" inputs and outputs, with all business logic shared between them.

LLMs are quite good at tedious tasks such as keeping multiple GUIs in different languages in sync with each other.

I couldn’t disagree more, when it comes to UIs. They should match the platform they are being used on. Cross-platform always produces a very sub-par experience. But us developers tend to care primarily about what makes development easiest for us.

I also don't care how if things _look_ native, I care if the work like a native app. For example, on the rare occasions I touch Windows, I expect standard keyboard shortcuts to work. On macOS, I expect full integration with the accessibility frameworks and OS affordances like services.

A lowest common denominator idea of "everywhere" is just not that useful.
