I think they address some different use cases. Electron makes cross platform frontends easier (at least across desktop OSes and web), but it doesn't really address typical OS-level concerns. Most web apps don't need to go that low, they just deal with the UI and business logic. Where they need higher performance, they can also spin off individual worker threads (in WASM or JS) for compute work, without touching the OS. Maybe high-performance web gaming? Or hardware dependent encoding etc.? But otherwise, I think the typical web app would benefit from a shared UI framework... which is different from a shared OS. You can have one without the other, kinda like how MUI (the Material React UI kit) runs on any browser and doesn't care about the OS, while Linux runs everywhere too but never looks the same on any two machines.
