I wouldn't say that is true. For something like React Native, the apps are plenty fast as JS is just used as an expressive control layer for the heavy lifting done in native code. I think a well maintained React Native for desktop is a really good way forward. People don't really care about a native "look and feel" any more so long as it's pretty, consistent, and integrates into the OS. Which is why electron is popular. I think the slowness of having everything rendered by a webview is the main drawback of electron, which is solved by React Native which only needs to run JSC or V8 somewhere.
