> It's uniquely inconsistent (many distinct toolkits with irreconcilable look-and-feel, even in the base system)
While I agree that Windows has long since abandoned UI/UX consistency, it's not like that is unique: On desktop Linux I regularly have mixed Qt/KDE, GTK2, GTK3+/libadwaita and Electron (with every JS GUI framework being a different UI/UX experience) GUIs and dialogs. I'm sure libcosmic/iced and others will be added eventually too.
