As a native desktop app developer, I feel like on the contrary it's very important to insulate from most of the OS APIs as users have come to expect availability on whatever desktop platform they are using. The Discord app has great UX and UI, arguably better than most native app and is exactly the same across all desktop OSes. "Apple tried and tested frameworks", what does that even means. It's not like other OSes come with buggy APIs.
I want the apps on my machine to have standard conventions for that platform, not alien conventions.
Having a standard UX across platforms optimized for the uncommon case. The more common case is that the user sticks to one platform so learning an astandard set of conventions is a barrier.
