It's certainly very desirable, which means the fact that it doesn't exist already is a huge red flag. Looking at the mobile space as a corollary, there still isn't a decent cross-platform Android/iOS UI library. Is Xamarin even still a thing? Not only would you have the same issues but more with Windows v. MacOS given the long legacy history of Windows UI compared to Android, but if you want it to be truly cross-platform you've got a couple thousand incantations of Linux-style systems to deal with as well. Based on market share alone[0] going Windows-only seems like a totally fine tradeoff if you want a native GUI.
