It will never have this since it's incapable of using native widgets and theming

You can criticize Electron’s performance and memory footprint, but as long as there’s an API to access something, it can access the same features as a native app, it just depends on the company’s willingness to do it. HTML is also one of the best platforms in terms of accessibility.

The problem though, is that cross-platform apps are optimized for that: sharing the same code among systems, and using specific OS features complicate things, so the tendency is to use the same solution for all of them, even when it isn’t the correct one. Also, they make it possible for developers who don’t know a certain OS well to still build for it, making things potentially worse in the user experience.
