Electron is basically a standalone browser tab. This is quite resource expensive. If WASM apps simply use their own rendering, ie the Qt Toolkit they get a much more native feel on top of having a rendering engine that is more optimized for out of browser use (due to not having a DOM, etc.) It would also slim down the applications a lot, notably when you dynamically link against the toolkit (which also means you share the lib with other apps instead of every app having it's own copy of electron)
