> Any custom framework will always feel wrong and out of place

Pretty sure that's the wrong metric. Users don't care if the interface doesn't look exactly like the rest as long as it's good looking and feels familiar.

As a heavy VSCode user for example, I don't think it feels out of place on a mac for example. The UI is consistent in itself, and the UX is consistent with the global UX of the OS (more so than some native mac apps like Finder for instance).

The main reason I hated Java Swing apps was that they were ugly as hell, not that they didn't feel native.
