For small apps, there would be another way. Instead of bundling the web runtime with each app, they could use the system-provided web runtime instead. Both macOS and Windows contain a competent modern browser engine (WebKit on Mac, Edge on Windows). This engine is typically already loaded in memory. By using the system-provided runtime, Electron-style apps could become much slimmer both in terms of on-disk footprint and RAM usage.

I’ve just released the first version of a runtime named Electrino which does exactly this.
